Here's my entry for the comp.
It's a simulation of bacteria and mold.
The bacteria have a few plans
1. Subdivide!
2. Move away from overcrowded areas
3. Avoid stress by aligning with the local bugs
The mold has one plan
1. Kill bacteria!
Press the spacebar to enter into debug mode. The red blocks indicate the population density, the green arrows with the blobs on the end indicate which way a bacteria should move to get away from the crowd. White circles are the mold.
Alt-Enter to go full screen (800x600x60)
Let me know if it's too slow for you and I'll make one with fewer bugs.
Have a lot of fun!
Jim
<edit> fixed the bug which was making it go in debug mode and crash on exit
