The Big Bang Theory - Rock, Paper, Scissors, Lizard, Spock.
And if 5 choices (RPS5) is not enough variation for you, you can try your, umm, hand at an online version of RPS7, 9, 11, 15, or the brain-melting mother of all Rock Paper Scissors variants, RPS25, which includes, among other things, a sponge, a cockroach, dynamite and a nuke.
