I can only guess how much explosive glee AutoDesk Motion FX — a new free app from AutoDesk, the developer behind AutoCAD and the SketchBook line of apps — would have engendered in me as a little kid, because I fostered a deep yearning to run around with a flaming hand or fire leaping from the top my head like some Ghost Rider clone. Good thing my parents kept me well away from matches and gasoline.
Check out the video above and you’ll get an idea of what the app is capable of. Best of all, it’s free. The catch? Motion FX only runs on Lion, because it employs facial-tracking technology embedded in the OS.
