Some friends and I play rock-paper-scissors (a.k.a. rochambeau) a whole lot, and the other day I mentioned that I'd read in a magazine a quote from a TV show that referred to an expanded RPS game. The TV show was "The Big Bang Theory," but that show didn't create the expanded RPS game. It's been around for years, and it's Rock Paper Scissors Spock Lizard. Here's an illustration:

"Paper disproves Spock" is brilliant. But, when I was doing research, I discovered that someone else has created a rochambeau game that includes 7, 9, 11, 15, and even 25 symbols. Here's a part of the 25-symbol rock-paper-scissors, which they sell as a poster:

But 25 wasn't enough, so they created a 101-gesture RPS game:

You can buy that in poster form here. There's no real reason for me to share this information with you at this particular time, I just think it's super-cool.
