Waiting for CS5: Collision Grid Test

This is an experiment I've been working on that uses grid collision and object radius proximity to animate objects. The idea here would be that this basic logic for random movement and object tracking should be applicable to a number of game scenarios.  Once Flash CS5 comes out I fully intend to make the investment and get to work on testing out how well Flash iPhone apps are able to keep up with the framerates and math required to pull this off. 

Then... I will build a game or two!
