Technology Notes: 
The playing field is projected onto a wall. Players can draw lines on it with differently coloured lasers (green and red are supported). Laser detection is done using a webcam and some clever filters.
Installation Instructions: 

Unzip, and run hell.py. Your webcam should be pointing at the projector. Move the game window onto the projector and hit enter.
