More Wiimote hackery takes today's honor as the second-most-watched YouTube game video. (The Halo 3 commercial is still scoring big, taking the top spot.) The video, created by the same people who demonstrated GlovePIE, shows the Wiimote controlling Half-Life 2.
The game interprets the movements of the Bluetooth controller, looking up and down with tilts, and left and right with rolls. The buttons are mapped to handle other game controls, like walking, normally driven by a keyboard. And yes, it's all done on a MacBook Pro running Windows XP; we thought that laptop looked familiar in the previous video.
