Why don’t you try a nice Silverlight game on Facebook?
Roshamboom! is inspired by David C. Lovelace’s extreme rock-paper-scissors concept called RPS-101. The RPS-101 (http://umop.com) game got a ton of web chatter when it was released back in 2007 because it took David over a year to concept the game and produce the 5000+ outcomes. The Plexipixel folks thought it would make an ideal (and silly) turn-based game for Facebook. Plus, it allowed them to practice some Silverlight skills."
