It's a keyboard wrapped around a pole.
Rotate it, and you can play in a different key or mode.
Run your finger along it, and you've got a scale.
I suppose what makes this useful is the ability to find scales and
modes more easily, with one downside: you've got to play a pole. (See
the video if you're having a hard time imagining how that will look the
next time your band wants to play Secret Agent Man.) (via ektopia)
that downside is a pretty large downside..
however, this might be well suited for female keyboard player who may suffer from ehhem pole envy.
I have one on order. Maybe most guys feel intimidated by a two-foot pole, but the implementation of this looks to be fantastic. Get over the shape of it already.

I've got another one on order. I'll talk soon about it.
