How It's Made...

Download the file here: kaleidoscope.js

Things that work well:

Page UI: The old UI relied entirely on key presses to turn things on. Radio buttons are much more intuitive.
Class/Object Structure: All objects have an update and draw function that makes it easy to update multiple objects of different classes at once.

Things I'd like to impove:

Rotation Speed Controls: Right now, rotation speeds are randomized. It would be nice to have a slider to control it.
Only 3 Drawing Modes Look Good: ..... yup.
More Kalideoscope-like: an actual kalideoscope has more unpredictable shapes than this one.
