We all saw how well the Windows XP on Intel Mac contest worked, so why not do something similar for the iSight? As you may know, the iSight is the popular Apple webcam that may be discontinued, due to all the new machines—iMac, MacBook, MacBookPro—coming with a built in iSight. Ignoring the Mac Mini of course.
So, this user wants to use the iSight mic on his Windows XP machine. Problem? No drivers. He's offering the same kind of bounty—people pitch in, winner collects, everyone wins—for someone to create an iSight driver and release it into open source. The pot's for Win XP only, but if someone wants to make a Vista version that's outside the requirements of this contest. Hackers have 6 months to make a driver, or he's going to return everyone's money. Get to work.
