A few buddies of mine are working on a project for next month's European tour of ISAM by AMON TOBIN. This stuff is pretty cutting-edge and something you'll begin to see much more of throughout the electronic music scene.
(Sorry for the poor video resolution - this stuff is very hard to capture in the dark, but use your imagination. It's absolutely incredible live given the true 3d effect.)
Video mapping takes a blank canvas [see below] and uses very large projectors (upwards of 80k each) to project moving images and effects. This has been done on the sides of buildings - with a popular effect being the deconstruction and reconstruction of the building. This is one of the first times being used for an electronic music tour.


I would highly recommend anyone in the London, Brussels, Berlin, Montreal area check it out next month! You won't be disappointed.
