multitouch, gesture recognition, no touch, LCD trackpads -- if you can think of it, somebody has probably done a version of it. Take this particular one for example, which just might rank below even the touchscreen GBA in terms of practical usefulness -- though, it's not as if utility is a prerequisite of joviality, right? If you've been neglecting that DIY muscle of late, you owe it to yourself to check out the video beyond the break, which shows that a humble touchpad can learn new tricks. Oh, and if you feel extra inspired, the read link contains another video plus the necessary code for making the light show happen. Don't say we never gave you anything.
