From the website:
Media Artist Toshio Iwai [creator of Electroplankton] and YAMAHA have collaborated to develop a new digital musical instrument for the 21st century, TENORI-ON.
There is a video on YouTube of Iwai demonstrating the device at a recent conference. The “performance” part of the video starts around halfway through and it is absolutely amazing.
Wow that is awesome! Sadly I think that even an instrument like that won’t make up for my lack of musical talent!
