The Internet’s Keyboard by Art Lebedev
Optimus Popularis is a slim keyboard design by Lebdebev with totally customizable keys that can be programmed with any function you desire. You then assign it a symbol, or even a video clip up to 10 frames (hell, make it a cat GIF!), that is displayed on an LED beneath the key. The long strip between the function and number keys is another programmable display, my vote for is for scrolling, blinking marquee text, AOL-style. Available for purchase at artlebedev for $1,086 USD, 747 €.
