Labelling something "the sickest thing on the Web" can be a bit of a stretch these days, but this certainly has to come close. Kaboom! is an online game where you pretend to be a suicide bomber. As the man in military fatigues runs back and forth across the screen, the goal is to pick the spot where you can kill or maim as many people as possible. Then click the mouse and, er, kaboom! This has already got the attention of the U.S. Congress, among others. Who says video games don't represent real life?
