EatEmUp

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.
