multitouch
since i have heard of lemur i wanted to try a multitouch display. i later found instructions on instructables.com showing how to build an DYI-Multitouch Display using a pictureframe, some infrared leds, a modified webcam and a lcd projector .
i dont own a lcd projector and so my multitouch display still remained a dream.
but recently i found a blog-post showing how to build a "moultitouch light". This version doesnt use infrared but normal light and it doesnt display the picture on the display but uses a second monitor.
i quickly hacked together my own version 
and managed to get some of the demos running :-) - VEEEEERY COOL
(aehm - yes the penguin is a webcam)
i didnt manage to get the flash demos running on linux but the smoke demo and the calibration tool are working now
