Over at video storage ubersite YouTube, fairly recent uploads (thanks for the tip, Tkoch!) include part of a Toshio Iwai interactive music demonstration video from last year's Spanish ArtFutura 2005 festival, where-in the Japanese artist and Electroplankton creator demonstrates some of the music art pieces that directly inspired the Nintendo DS title.

There's a Spanish-language report on Iwai's appearance last October over at VidaExtra, but YouTube (thanks to Hardware12V) also hosts another part of Iwai's presentation, an awesome video demo of Iwai's Tenori-On, a new digital musical instrument co-created by Iwai and Yamaha, and incorporating many of Iwai's overarching themes also explored in Electroplankton. Awesome stuff.
