The two biodome cities request that you connect them together with BOTH pipe systems! Connect both brown and slate(?) colored pipes to both cities without any gaps. Pipes rotate randomly every 5 seconds due to "environmental conditions" and "rebels".

Source requires Python 3 and pyglet 1.2a1 (not included, available at https://code.google.com/p/pyglet/downloads/list?q=1.2alpha1)

Controls:
- Left mouse: Pick up piece -> swap piece
- Right mouse: Rotate piece
- ESCAPE: Pause
- Q: Quit when paused
- F: Show framerate

Known bugs:
- Some graphical errors due to precision loss from rotating
- Unable to drop piece where it was picked up from [fixed]
- Both pipe colors do not need to be connected at the same time [fixed]
