Ok, not sure if this is "Da Spot" for this but here goes - I'm always trading website url's with friends, places that have unique things, crazy stuff, the weird, the wacky. It's unbelievable what's on the Web.
I like The Lifesaver's Candystand site. If you go there, check out the Billiards Game. It's a pretty near functional pool game played with your mouse, and can be played with 1 or 2 players, I may be the last one to hear about it, but I thought it was cool so if you haven't, you might want to check it out!
