It's not quite a game, according to PixelJunk 4am lead designer Rowan Parker. It's more of a digital musical instrument.

It seems more like an experiment than a true game. It sounds a bit like the PlayStation 3 version of the DS game, Electroplankton. Whatever it is, or will be, it will be available in the Spring, and it will have Move functionality.

Also, I have no idea what is going on the screenshot above. Feel free to speculate in the comments below.
