So someone configured their Wii-Mote to work on their PC, nothing new. They then mapped the buttons to a Dreamcast emulator, and booted up one of my all time favourite games, Rez.
Now the project author claims that he's mapped the motion of the target to both the nun-chuck analog stick, as well as the motion sensor in the Wii-mote. There's no way to prove that he was actually successful in getting the target to respond to the Wii-motes movements, but I'm sure it's not impossible
The project is cool, if only to show what can be done with the Wii-mote, and how it has got some people to re-examine some of the old games, and see them in a new light.
