The idea is to take advantage of all these computers sitting idle at night (and often during the day too), that could run these calculations for us. But it also has to be secure, and the calculations should stop when the normal user needs its computer at its full speed. So basically, you want it to be just like a screensaver, only popping up when you don't need your computer."
Their goal is to reach something like 200Ghz, and apparently there is a super sweet widget that you can get that tells you how high their speed is.
So join up, and help reach their goal.
