Instant clay animation
Check out this “Instant Claymation machine” on WMMNA – “Animaatiokone (Animation Machine) is an installation that turns you into a master clay animator. It’s built of a potato peeling machine, a laptop PC and pinball machine buttons. First you sculpt clay actors. When you’re happy with your cast, you locate the characters inside the mini-studio (inside the Animaatiokone machine), move the actors and capture frames. An overhead display allows you to check the shooting, you can also delete or add frames on the touch of a button. When you’re finish, you can add a soundtrack.” [via] Link.

Nice use of a mint tin! – “This site features projects and circuits for building stereo microphones from low-cost Panasonic electret microphone capsules. Included are Mid-Side, XY, and Blumlein microphone setups. In addition, there are interesting related circuits and links to sites with microphone information and parts sources.” 
The Goldfish Online has some really interesting LEGO logic gates – “…designed working NOT, OR, NOR, AND, and NAND gates. Using two NAND gates I have produced a NAND gate latch or Flip-FLop. The natural follow on from these is clocked logic, full-adders and ultimately a genuine “computer” device. At the moment all these gates essentially just demonstrators. They work, but because of the limitations that arise through gear slippage, the real practicable use is probably not that great.” The details of logic gates can be found here – 
Fanjita writes “Following on from Tetris for GTA, I’ve put together a small package of source and useful tools for developing homebrew to run with the GTA loader. This package will allow you to replace tetris.bin with your own binary, and makes it easy to deal with some of the issues in the GTA environment. I’m hoping that developers (especially v2.6 owners) will use this package to develop simple homebrew to keep v2.6 users entertained while they wait for their firmware to be fully exploited.”
