Visualisation for the Insen Tour of Alva Noto & Ryuichi Sakamoto in 2005 and 2006. This one i did within an hour when i had access to the complete LED screen for the first time. The tour had already started. When you would display just one colour on the whole screen you could see the edges of each LED module. So i just used these edges for the display of the lines.
Each stroke of a key on Sakamotos Yamaha Disklavier would send out a MIDI signal that would call a random preset of predefined patterns on the screen.
