|
||||
2. Or click "View Interactive Demos" from the home page
|
||||
|
||||
### Searching Demos
|
||||
- Type in the search box to filter by:
|
||||
- Demo name
|
||||
- Description text
|
||||
- Type
|
||||
- Feature names
|
||||
|
||||
### Filtering by Category

|
||||
- Click "All Demos" to reset
|
||||
|
||||
### Launching a Demo
|
||||
- Click anywhere on a demo card
|
||||
- Or click the "Launch Demo →" link
|
||||
|
||||
## Maintenance
|
||||
|
||||
### Adding New Demos
|
||||
Edit `/app/demos/page.tsx`:
|
||||
|
||||
```typescript
|
||||
const demos: Record<string, Demo[]> = {
|
||||
categoryName: [
|
||||
{
|
||||
number: X,
|
||||
title: 'Demo Title',
|
||||
description: 'Demo description...',
|
||||
path: '/demo-route',
|
||||
type: 'Demo Type',
|
||||
status: 'complete' | 'beta' | 'prototype',
|
||||
features: ['Feature 1', 'Feature 2', ...],
|
||||
milestone: 'Optional milestone note'
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Updating Categories
|
||||
Add to the `categories` array:
|
||||
|
||||
```typescript
|
||||
{
|
||||
id: 'categoryKey',
|
||||
label: 'Display Name',
|
||||
count: demos.categoryKey.length,
|
||||
icon: '🔬'
|
||||
}
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Current Performance
|
||||
- Minimal bundle size (no heavy dependencies)
|
||||
- Client-side rendering with static demo data
|
||||
- Fast search (no API calls)
|
||||
- Instant category filtering
|
||||
|
||||
### Optimization Opportunities
|
||||
- Lazy load demo screenshots
|
||||
- Virtual scrolling for many demos
|
||||
- Server-side rendering for initial load
|
||||
- Static generation at build time
|
||||
|
||||
## Accessibility
|
||||
|
||||
### Current Features
|
||||
- Semantic HTML structure
|
||||
- Keyboard navigation support
|
||||
- Focus states on interactive elements
|
||||
- High contrast color schemes
|
||||
|
||||
### Future Improvements
|
||||
- ARIA labels for all interactive elements
|
||||
- Screen reader optimizations
|
||||
- Keyboard shortcuts
|
||||
- Focus management
|
||||
|
||||
## Design Philosophy
|
||||
|
||||
### Post-Appitalism Alignment
|
||||
- **Transparent**: All demos visible and accessible
|
||||
- **Exploratory**: Encourages browsing and discovery
|
||||
- **Educational**: Descriptions explain what each demo teaches
|
||||
- **Beautiful**: Aesthetically compelling design
|
||||
- **Functional**: No unnecessary complexity
|
||||
|
||||
### User Experience Goals
|
||||
1. **Immediate Value**: See all demos at a glance
|
||||
2. **Easy Discovery**: Search and filter make finding demos trivial
|
||||
3. **Clear Status**: Know which demos are production-ready
|
||||
4. **Feature Visibility**: Understand what each demo offers
|
||||
5. **Quick Access**: One click to launch any demo
|
||||

# Flow-Based Flow Funding Module
|
||||
|
||||
**Status**: Initial Implementation Complete ✅
|
||||
**Route**: `/tbff-flow`
|
||||
**Last Updated**: 2025-11-09
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
This module implements a **flow-based** visualization of Flow Funding, focusing on resource circulation rather than accumulation. Unlike the stock-based model (`/tbff`), this visualizes how resources move through networks in real-time.
|
||||
|
||||
## Core Concepts
|
||||
|
||||
### Flow vs Stock
|
||||
|
||||
**Stock Model** (`/tbff`):
|
||||
- Accounts have balances (accumulated resources)
|
||||
- Distribution adds to balances
|
||||
- Thresholds define states (deficit, healthy, overflow)
|
||||
- Overflow triggers redistribution
|
||||
|
||||
**Flow Model** (`/tbff-flow`):
|
||||
- Nodes have flow rates (resources in motion)
|
||||
- Flow continuously circulates
|
||||
- Thresholds define absorption capacity
|
||||
- Real-time animation shows circulation
|
||||
|
||||
### 1. Flow Node
|
||||
|
||||
Each node receives flow, absorbs what it needs, and passes excess onward.
|
||||
|
||||
**Properties**:
|
||||
- `minAbsorption`: Minimum flow needed to function (survival level)
|
||||
- `maxAbsorption`: Maximum flow that can be absorbed (capacity)
|
||||
- `externalFlow`: Flow injected by user (source)
|
||||
- `inflow`: Total flow entering (external + from allocations)
|
||||
- `absorbed`: Amount kept (between min and max)
|
||||
- `outflow`: Excess flow leaving (to allocations)
|
||||
|
||||
**Status**:
|
||||
- 🔴 **Starved**: absorbed < minAbsorption
|
||||
- 🟡 **Minimum**: absorbed ≈ minAbsorption
|
||||
- 🔵 **Healthy**: minAbsorption < absorbed < maxAbsorption
|
||||
- 🟢 **Saturated**: absorbed ≥ maxAbsorption
|
||||
|
||||
### 2. Flow Propagation
|
||||
|
||||
**Algorithm**:
|
||||
1. Start with external flows (user-set inputs)
|
||||
2. For each iteration:
|
||||
- Calculate absorption: `min(inflow, maxAbsorption)`
|
||||
- Calculate outflow: `max(0, inflow - absorbed)`
|
||||
- Distribute outflow via allocations
|
||||
- Update inflows for next iteration
|
||||
3. Repeat until convergence (flows stabilize)
|
||||
4. Create overflow sink if needed
|
||||
|
||||
**Convergence**: Flows change by less than 0.01 between iterations
|
||||
|
||||
### 3. Overflow Sink
|
||||
|
||||
**Auto-created** when network has unallocated outflow.
|
||||
|
||||
**Purpose**: Capture excess flow that has nowhere to go
|
||||
|
||||
**Behavior**:
|
||||
- Appears automatically when needed
|
||||
- Disappears when no longer needed
|
||||
- Infinite absorption capacity
|
||||
- Visualized with "SINK" label
|
||||
|
||||
### 4. Flow Particles
|
||||
|
||||
**Animation**: Particles move along allocation arrows
|
||||
|
||||
**Properties**:
|
||||
- Position along arrow (0.0 to 1.0)
|
||||
- Amount (affects size and color)
|
||||
- Speed (faster for higher flow)
|
||||
- Continuous loop (resets at end)
|
||||
|
||||
**Purpose**: Visual feedback of resource circulation

||||
- Status colors (red/yellow/blue/green)
|
||||
- Arrow thickness = flow amount
|
||||
- Particle density = flow volume
|
||||
- External flow indicators (green dots)
|
||||
|

|
||||
|
||||
## Usage
|
||||
|
||||
### Setting Flow
|
||||
|
||||
1. Select a node (click on it)
|
||||
2. Enter external flow value in sidebar
|
||||
3. Watch flow propagate automatically
|
||||
4. See particles animate along arrows
|
||||
|
||||
### Creating Allocations
|
||||
|
||||
1. Click "Create Arrow" tool
|
||||
2. Click source node
|
||||
3. Click target node
|
||||
4. Allocation created with 50% default
|
||||
5. Flow re-propagates automatically
|
||||
|
||||
### Observing Flow
|
||||
|
||||
- **Inflow bars** (blue): Total flow entering
|
||||
- **Absorption bars** (status color): Amount kept
|
||||
- **Outflow bars** (green): Excess leaving
|
||||
- **Particles**: Moving resources
|
||||
- **Arrow thickness**: Flow amount
|
||||
|
||||
### Keyboard Shortcuts
|
||||
|
||||
- **Space**: Pause/play animation
|
||||
- **Escape**: Cancel creation, deselect
|
||||
- **Delete**: Remove selected allocation
|
||||

## Sample Networks
|
||||
|
||||
### 1. Linear Flow
|
||||
|
||||
**Structure**: A → B → C
|
||||
|
||||
**Setup**: Alice receives 100 flow, passes excess to Bob, who passes to Carol
|
||||
|
||||
**Demonstrates**: Sequential absorption and propagation
|
||||
|
||||
### 2. Split Flow
|
||||
|
||||
**Structure**: Source → Projects (A, B) → Commons
|
||||
|
||||
**Setup**: Source splits 60/40 between projects, which merge at Commons
|
||||
|
||||
**Demonstrates**: Branching and merging flows
|
||||
|
||||
### 3. Circular Flow
|
||||
|
||||
**Structure**: A → B → C → A
|
||||
|
||||
**Setup**: Alice injects 50 flow, which circulates continuously
|
||||
|
||||
**Demonstrates**: Circular resource circulation
|
||||
|
||||
### 4. Empty Network
|
||||
|
||||
**Structure**: 3 unconnected nodes
|
||||
|
||||
**Purpose**: Build custom flow patterns from scratch
|
||||

## Algorithm Details
|
||||
|
||||
### Flow Propagation Example
|
||||
|
||||
```
|
||||
Initial State:
|
||||
Alice: externalFlow = 100, maxAbsorption = 50
|
||||
Bob: externalFlow = 0, maxAbsorption = 30
|
||||
Alice → Bob (100%)
|
||||
|
||||
Iteration 1:
|
||||
Alice: inflow = 100, absorbed = 50, outflow = 50
|
||||
Bob: inflow = 0 (not yet received)
|
||||
|
||||
Iteration 2:
|
||||
Alice: inflow = 100, absorbed = 50, outflow = 50
|
||||
Bob: inflow = 50, absorbed = 30, outflow = 20
|
||||
|
||||
Iteration 3 onwards:
|
||||
(Converged - no change)
|
||||
|
||||
Result:
|
||||
Alice absorbs 50, passes 50 to Bob
|
||||
Bob absorbs 30, has 20 outflow (needs overflow node)
|
||||
```
|
||||
|
||||
### Convergence
|
||||
|
||||
**Condition**: `max(|inflow[i] - inflow[i-1]|) < 0.01` for all nodes
|
||||
|
||||
**Max Iterations**: 100
|
||||
|
||||
**Typical**: Converges in 10-20 iterations for most networks
|
||||
|
||||

|
||||
|
||||
## Technical Implementation
|
||||
|
||||
### State Management
|
||||
|
||||
```typescript
|
||||
const [network, setNetwork] = useState<FlowNetwork>(...)
|
||||
const [particles, setParticles] = useState<FlowParticle[]>([])
|
||||
const [isAnimating, setIsAnimating] = useState(true)
|
||||
```
|
||||
|
||||
### Animation Loop
|
||||
|
||||
```typescript
|
||||
useEffect(() => {
|
||||
const animate = () => {
|
||||
setParticles(prev => updateFlowParticles(prev))
|
||||
requestAnimationFrame(animate)
|
||||
}
|
||||
requestAnimationFrame(animate)
|
||||
}, [isAnimating])
|
||||
```
|
||||
|
||||
### Canvas Rendering
|
||||
|
||||
```typescript
|
||||
useEffect(() => {
|
||||
renderFlowNetwork(ctx, network, width, height, particles, ...)
|
||||
}, [network, particles, selectedNodeId, selectedAllocationId])
|
||||
```
|
||||
|
||||
### Flow Propagation Trigger
|
||||
|
||||
- On network load
|
||||
- On external flow change
|
||||
- On allocation create/update/delete
|
||||
- Automatic 100ms after change
|
||||

||||

||||
## Design Decisions
|
||||
|
||||
### 1. Why Separate from Stock Model?
|
||||
|
||||
**Decision**: Create `/tbff-flow` as separate route
|
||||
|
||||
**Reasoning**:
|
||||
- Different mental models (flow vs stock)
|
||||
- Different visualizations (particles vs bars)
|
||||
- Different algorithms (propagation vs distribution)
|
||||
- Users can compare both approaches
|
||||
|
||||
### 2. Why Real-Time Continuous Animation?
|
||||
|
||||
**Decision**: Particles move continuously at 60fps
|
||||
|
||||
**Reasoning**:
|
||||
- Emphasizes circulation over states
|
||||
- More engaging and dynamic
|
||||
- Matches "flow" concept intuitively
|
||||
- Educational - see resources in motion
|
||||
|
||||
**Trade-off**: More CPU usage vs better UX
|
||||
|
||||
### 3. Why Auto-Create Overflow Node?
|
||||
|
||||
**Decision**: Automatically create/remove overflow sink
|
||||
|
||||
**Reasoning**:
|
||||
- Unallocated outflow needs destination
|
||||
- Prevents "leaking" flow
|
||||
- Conserves resources (total inflow = absorbed + overflow)
|
||||
- User shouldn't have to manually manage
|
||||
|
||||
### 4. Why Absorption Thresholds?
|
||||
|
||||
**Decision**: Min/max thresholds define absorption capacity
|
||||
|
||||
**Reasoning**:
|
||||
- Maps to real resource needs (minimum to function, maximum to benefit)
|
||||
- Similar to stock model (easy to understand)
|
||||
- Allows partial absorption (not all-or-nothing)
|
||||
- Generates meaningful outflow for circulation
|
||||
|
||||

|
||||
|
||||
## Comparison with Stock Model
|
||||
|
||||
| Aspect | Stock Model (`/tbff`) | Flow Model (`/tbff-flow`) |
|
||||
|--------|----------------------|---------------------------|
|
||||
| **Core Metric** | Balance (accumulated) | Flow rate (per time) |
|
||||
| **Visualization** | Fill height | Flow bars + particles |
|
||||
| **Input** | Add funding (one-time) | Set flow (continuous) |
|
||||
| **Algorithm** | Initial distribution | Flow propagation |
|
||||
| **Animation** | Static (for now) | Real-time particles |
|
||||
| **Overflow** | Triggers redistribution | Continuous outflow |
|
||||
| **Use Case** | Budget allocation | Resource circulation |
|
||||
|
||||

|
||||
|
||||
### Phase 4

# Screenshot Management
|
||||
|
||||
This directory contains scripts for managing demo screenshots.
|
||||
|
||||
## Capturing Screenshots
|
||||
|
||||
### Prerequisites
|
||||
- Development server must be running (`pnpm dev`)
|
||||
- All demo pages should be accessible at their routes
|
||||
|
||||
### Running the Screenshot Script
|
||||
|
||||
```bash
|
||||
# Make sure dev server is running first
|
||||
pnpm dev
|
||||
|
||||
# In another terminal, capture screenshots
|
||||
pnpm screenshots
|
||||
```
|
||||
|
||||
This will:
|
||||
1. Launch a headless Chrome browser
|
||||
2. Navigate to each demo page
|
||||
3. Wait for content to load
|
||||
4. Capture a 1280x800 screenshot
|
||||
5. Save to `public/screenshots/`
|
||||
|
||||
### Output
|
||||
|
||||
Screenshots are saved as:
|
||||
- `public/screenshots/tbff.png`
|
||||
- `public/screenshots/tbff-flow.png`
|
||||
- `public/screenshots/flow-v2.png`
|
||||
- `public/screenshots/italism.png`
|
||||
- `public/screenshots/flowfunding.png`
|
||||
|
||||
### Adding New Demos
|
||||
|
||||
To capture screenshots for new demos, edit `capture-screenshots.mjs`:
|
||||
|
||||
```javascript
|
||||
const demos = [
|
||||
{ path: '/your-new-demo', name: 'your-new-demo' },
|
||||
// ... existing demos
|
||||
];
|
||||
```
|
||||
|
||||
Then update `app/demos/page.tsx` to include the screenshot path:
|
||||
|
||||
```typescript
|
||||
{
|
||||
title: 'Your New Demo',
|
||||
path: '/your-new-demo',
|
||||
screenshot: '/screenshots/your-new-demo.png',
|
||||
// ... other properties
|
||||
}
|
||||
```
|
||||
|
||||
## Screenshot Specifications
|
||||
|
||||
- **Viewport**: 1280x800 pixels
|
||||
- **Format**: PNG
|
||||
- **Wait Time**: 2 seconds after page load (for animations to settle)
|
||||
- **Network**: Waits for networkidle2 (most network activity finished)
|
||||
|
||||
## Customization
|
||||
|
||||
### Changing Viewport Size
|
||||
|
||||
Edit the viewport in `capture-screenshots.mjs`:
|
||||
|
||||
```javascript
|
||||
await page.setViewport({
|
||||
width: 1920, // Change width
|
||||
height: 1080 // Change height
|
||||
});
|
||||
```
|
||||
|
||||
### Changing Wait Time
|
||||
|
||||
Adjust the timeout if demos need more time to render:
|
||||
|
||||
```javascript
|
||||
await new Promise(resolve => setTimeout(resolve, 3000)); // 3 seconds
|
||||
```
|
||||
|
||||
### Capturing Specific Section
|
||||
|
||||
To capture only part of a page:
|
||||
|
||||
```javascript
|
||||
const element = await page.$('.demo-container');
|
||||
await element.screenshot({ path: screenshotPath });
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Screenshots are blank
|
||||
- Increase wait time
|
||||
- Check if content loads in actual browser
|
||||
- Ensure dev server is running
|
||||
|
||||
### Browser launch fails
|
||||
- Check if puppeteer installed: `pnpm list puppeteer`
|
||||
- Reinstall: `pnpm add -D puppeteer`
|
||||
- Check system dependencies for Chrome
|
||||
|
||||
### Timeout errors
|
||||
- Increase timeout in script:
|
||||
```javascript
|
||||
timeout: 60000 // 60 seconds
|
||||
```
|
||||
|
||||
## Manual Screenshot Workflow
|
||||
|
||||
If automated screenshots don't work:
|
||||
|
||||
1. Open demo in browser
|
||||
2. Set window to 1280x800
|
||||
3. Use browser screenshot tool (F12 → Device Toolbar → Screenshot)
|
||||
4. Save to `public/screenshots/[demo-name].png`
|
||||
5. Update demo card with screenshot path
|
||||
|
||||
## Performance Tips
|
||||
|
||||
- Screenshots are cached by browser
|
||||
- Total size: ~560KB for 5 demos
|
||||
- Consider optimizing PNGs with tools like `pngquant` or `imagemin`
|
||||
- WebP format could reduce size further
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
- [ ] Generate thumbnails in addition to full screenshots
|
||||
- [ ] Add WebP format support
|
||||
- [ ] Capture at multiple viewport sizes
|
||||
- [ ] Add screenshot comparison for regression testing
|
||||
- [ ] Automate screenshot capture on build
|
||||
- [ ] Add screenshot update on demo changes (CI/CD)
