## MicroSim spec
- **Recommended sim type:** reaction-[[Diffusion|diffusion]]

- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Energy input`
- `Dissipation`
- `Coupling`
### What animates
An ordered [[Structure|structure]] persists by burning through energy as input and dissipation change.
### Learning objective
Show how sustained energy flow maintains order far from equilibrium.

## Concept summary
A dissipative system is a thermodynamically open [[System|system]] which is operating out of, and often far from, [[Thermodynamic_equilibrium|thermodynamic equilibrium]] in an environment with which it exchanges [[Energy|energy]] and matter. A tornado may be thought of as a dissipative system.
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to systems thinking)
- [ ] Finalize parameter ranges and defaults
- [ ] Implement the p5.js sketch (drawing + control regions)
- [ ] Add caption + the learning objective on the page
- [ ] Set `status: done`
## p5.js sketch
```javascript
// MicroSim: Dissipative system
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render reaction-diffusion; respond live.
}
```
