Basic mechanics are:

• Press Space to get some color.
• Press r, g, and b (or 1, 2, and 3) to release color to get the hue you want.
• Bump into walls to make new rooms with your circle’s current color.
• If you make enough rooms, you get the ability to write notes on your rooms.
• If you write enough notes, you get the ability to put down single letters on any room.
• The world is shared among all users and updated for everyone in real time.

All I want to do now is add strange audio effects, maybe some zen koans to find, and polish up the UI.
