Majken got me hooked on an online game called iSketch. It's similar to Pictionary: a word or phrase is chosen randomly, and one player tries to draw it while the other players try to guess what it is. We play with the "computer terms" list, which includes phrases like "dynamic link library", "personal computer", "arithmetic and logic unit", "hexadecimal", "Mozilla", and "intranet".
I'm playing right now with a few friends from the Mozilla community. Come join us in the user-created room called "Foxymonkies"! IM me or email me your AIM screenname if you want me to IM you next time we play.
iSketch requires Shockwave. I've played on Windows and Mac, mouse and touchpad.
