Gestrument developer Jesper Nordin has been keeping very busy. In addition to further app development he's been working with a team out in France for a piece called Visual Exformation. A large light structure on the stage is "listening" to the musicians, and reacting dynamically to the performance. Although you can't see any iPhones in this teaser trailer, Jesper assures me they are there and running Gestrument!
