Impressive video, runs OSC.  $500 (ow!).  Open source on the drivers and
firmware but they don't say how to build it.  Anyone seen this in the
wild? Supposedly they're going to be shipping by two weeks ago.

I've read about it on many blogs in the past few months. I believe that the price is high because of the trendy design and the stylish pictures they made of the first prototypes.

If you want to try to make your own, the electronic circuit to make such thing should be pretty cheap (10-20$). Then you should find and buy those backlit buttons, but you can use a simple button with a led above it for a less futuristic, more retro style. Anyway, it shouldn't be difficult to find this kind of buttons on some online shop.

The firmware: one of the simplest assembly programs you can write. You can make it with the PIC 16f84 (5$) and a bunch of demultiplexer ICs.

The protocol is: just send this 64 bits (one for each button).
