I've not tried it yet but, though it always makes me feel guilty when I power up the PS3 and see the icon, but Stanford University's Folding@home Project has caught the imagination of a sizable number of PS3 owners. According to Vijay Pande, Folding@home program lead, the PS3 has helped "perform simulations in the first few weeks that would normally take us more than a year to calculate. We are now gearing up for new simulations that will continue our current studies of Alzheimer's and other diseases." A new update has also launched, boosting the calculation speed. And you can set it to run only when the PS3 is idle. Given the sorry state of the launch games it may be worth doing your bit now before the decent stuff starts arriving to monopolise your PS3's processor. So, is your PS3 contributing to Folding@home?
