I have their Vim3.3 screensaver, with the first model of a neural brain. That program simulates day/night cycles, and the creature (a nice girl) is always searching around that 3d world (although no shadows makes the effect a little weird) looking for seeds. Then, the creature finds places she like, and if she have seeds collected, she starts making a garden with those seeds. In fact, it's an interesting program, although the thing that impresses ppl is the visual thing, and not all the operations running inside it
and that need a bit more of work
Anyway, if you can, try the VIM instead of that falcon thingie.
