Attoparsec -- Ten Hundred Keyboard

An aluminum disk with semi-circular indents around its perimeter is mounted behind a vaguely art deco alumunum post, leaning slightly backwards. Set into a window in the post is a black plastic 7-segement display, with neon yellow segments currently reading 9.

I had wanted to make a ridiculously large keyboard for some time, but it wasn't until I thought of doing one for the "ten hundred" version of English introduced in the XKCD comic Up Goer Five that I finally did it. 1000 keys for the 1000 most common English words, plus another 20 utility keys to make it a (vaguely) functional keyboard.
