It's called a "viola organista", and it sounds absolutely gorgeous.
What it is is a keyboard that resembles a small grand piano that uses spinning wheels inside the piano to bow at the strings, rather than hammering them. The result is a keyboard that sounds like a string section on the low keys, and a reed organ in the higher ones (see video in article).
I don't know of this is really "Hot off the Press" material. I just felt like sharing it, and I didn't really know where else to put it.
