What can I say? It's the advantages of using a standard protocol for input devices... even though it took a lot of experimenting till "hackers" found out how to properly use all Wiimote functions.
If it's common to use Nintendos bluetooth Wiimote controller on the PC, this is slightly different: as you can now use it on your Nokia N810 MID.
Thanks to a small python script, your Nokia can now receive the Wiimote bluetooth commands and translate it into common X-Windows events (simulating keypresses and mouse clicks.)
