Man, anyone that plays strip poker with their computer seriously needs to get out more
Umm, back OT, I'd probably try and keep the graphics relatively simple... an animated "applet-style" game would be better written in flash than Java. So maybe some form of arcade game like Tetris with simple graphics but decent gameplay. Making it a real-time game (like Tetris) would also add a challenge as you would have to deal with several threads and stuff.
