Here's my chaos game sim I showed off over on Twitter yesterday!
EDIT: Fixed a bug with 2 edges, and also fixed some rounding issues.

Also, here's how to control this:

While viewing chaos:

• Z will open the menu.
• X will change rotate modes, but only if you have a finite amount of points.

While in menu:

• Left and Right will edit the current value.
• Up and Down will move your cursor.
• Z will close the menu.

Rotate modes go like this:

• Don't rotate
• Do rotate
• Do rotate, but you can control it with Left and Right.

EDIT 2: Added step option, which lets you run the chaos game faster.
EDIT 3: Added some more polish, including a tooltip to tell you about the menu.

Old versions (not sure why you need them, but)
