Just an interesting keyboard that I came across on the net
Link:Every key of the Optimus Maximus keyboard is a stand-alone display showing the function it is currently associated with.
Optimus is equally good for any keyboard layouts—Cyrillic, Ancient Greek, Georgian, Arabic, Quenya, hiragana—and so on to infinity: notes, numerals, special symbols, HTML codes, math functions, images etc.
I think its a cool idea. From what I can gather, each key on the keyboard can be programmed for a certain function. The key will then 'display' the appropriate symbol on it.
Not cool, the price. Looking at the store, looks like this sucker will put a dent in your wallet to the size of $1500.
