Another toy prototype. I've been playing with steering behaviours and implemented Reynolds "predator" and "evasion" behaviours.
You can play with it here.
The behaviour and environment is all procedurally generated (sorry!) Wind gusts a bit if you press the mouse. Camera follows the black birds around, the black birds hunt the red birds, and the red birds feed on the clouds...
Not very interactive but quite meditative if you watch it for a while.
I'm quite interested in exploring this idea some more and making something bigger with flocking / herding as a central mechanic.
