# Demo 2: Fixing an Issue, Adding a new Feature 

- `demo-01.index.html` has the output of a former run of `../demo1`
- There is an issue where the background flickers as the last few particles
  fade out. Smooth out the rapid color change.
- Add a new feature: clicking should cause a burst of particles as well as
  a shift in the overall hue.
- The output of a previous plan is in `old-plan.md`.
