I was browsing a mac forum, given that I'm considering buying one, and I came across this amusing piece of software: http://wolfire.com/lugaru.html#PageTop Apparently, it's a martial arts/adventure game starring an anthropomorphic bunny out to avenge the deaths and suffering of fellow bunnies. If the vid clips are any indication of how things actually work, it should be pretty cool. Too bad it's mac-only, though.
That game looks awesome.... I love their combination of emphasis on realistic hand-to-hand combat and giant bunnies.
