The Wii Drum Kit is another great example of a tangible user interface made possible with the Wiimote. The latest version adds support for the Nunchuck, so you can use both hands to play your virtual drum kit. This one is a Windows application, and source is available at the This is Not a Label blog.
The Wiimote + Nunchuck combination seems like the perfect interface for an air drum. Different gestures are used to trigger a specific drum, so the high hat is a flick to the side, the snare is a forward hit, etc. There’s no kick pedal, of course, but the fist stamping motion that’s used is a reasonable alternative.

making it the only open source volume encryption utility that works in Linux, Mac and Windows
For a given value of “works” (and really, for a given value of “open source” as well; the TrueCrypt license is a minefield for developers, and their own developers are actively hostile to outside contributors).
Both whole disk encryption and hidden containers are only available in the Windows versions. Linux and Mac support is very much just a token effort, and knowing the TrueCrypt developers, we’ll be waiting for the features the Windows version has had for ages for quite a while still.
