Here you can download the coolest screensaver that I've ever seen. While your computer is in idle mode and has its screensaver up, it sends requests to popular spam sites to use up their bandwidth thus costing the spammers buckets of money.

Lycos keeps it updated with lists of popular spamming sites.

I've installed it on my machine. Do your part in the war against spam and install it on your machine as well!
