Seconds of madness 
Seconds of madness is a fun flash game where you surf down a three-dimensional tube and try to avoid the obstacles that get in your way. I can only manage a high score of around 135 points, which is about 30 seconds of surfing. I'm sure you can do better. The real danger of this game though, is that it plays so quickly. You'll find yourself saying, "One more game." But after you say it a few times you'll understand that you've wasted an hour and all you have to show is a high score of 135 points. But enjoy and I'll try to dig up some good things for the rest of the week.
