i saw a brief article on this in popular mechanics, Googled it and found the site. this is just the coolest keyboard i've ever seen and i even think it might be the future of keyboarding if the price can be sub-50$ (but even thats a little pricey for a keyboard). check it out for yourself: http://www.artlebedev.com/portfolio/optimus/
the only issue i have with this is the mini screens on each key, they seem like they might be power-hungry and might not be able to run off the usb port's 5v (which is bad because i dont want to plug my keyboard into the wall..). i would rather see the screens be replaced with color e-ink displays (not mass-produced yet). those would be perfect for this application because of the low-power needed to operate them and the fact that they only use power when the image has to be changed (no power needed to sustain the image), and the image will only need to be changed on this keyboard when you switch an application. not to mention that the resolution will be better and it will look like a regular keyboard because e-ink screens look more like a sticker or printed paper that a LCD screen. read more about e-ink here: http://www.eink.com/
