I found this cool quiz application called Blufr, from Answers.com. It's a trivia quiz, and I've stuck a page up which you can play with in the left hand menu. It's addictive for know-nothings like me who foolishly sometimes think we know stuff.

The idea of it is to drive visits to Answers.com, which is actually a damn good resource. This makes it as much fun as using my desktop widget to go to wikipedia, but since you haven't go a mac, you don't yet know about the pleasures of widgets.
