Gravitron is a space based game where you must defeat your enemies solely by deflecting their bullets back to them.

Yeah, the help page needs work, and more levels are forthcoming. But the gameplay is pretty sweet as is, and there are a a bunch of cool enemies. suggestions/comments/bug reports are welcome.

This is a basic flocking implementation, demonstrating the organization and collection of many bodies in a cohesive group. The boids all follow the mouse, and are bounded to stay inside the screen.

EatEmUp is a cool Artificial Intelligence simulation, which shows a "bully in the playground" type situation -- one predator goes after many prey objects, which have different "fields of view" (as manifested by the semitransparent circles surrounding them). The predator simply goes after the closes one at any given moment.
At this point, the simulation is pretty cool as a screen saver, but has no real interactive functionality.

Here's a remake of the classic "Missile Command" -- currently in an early stage, but playable.

GuyBounce is a unique game in which you control multiple bouncing players at once -- using the same keys for all. The goal is to get them all into the "goal" area, signified by blue. It is written in python+pygame

Laserz originally began as just a sandbox with a laser and unlimited mirrors to play around with (which though unbelievably entertaining, didn't really have an objective ;). Now the point is to reflect a laser, which originates in the center, through all the targets on a given level, using a limited number of mirrors.

Ball Attack is a simple little arcade game -- reminiscent of pong or breakout, but you need to keep every increasing amounts of balls in the air with your little paddle.
