Frieder Weiss....

...is a Berlin-based computer engineer and musician and also the algorithm
conductor behind Glow, a new kind of dance and technology performance.
His technology allows the dancer's movements, captured by a camera on the
stage, to effectively generate an electronic shadow for the dancers. The data
is fed into a "palette" of computer algorithms which then create light and
video displays projected back onto the dancer and stage.
A special balance between the pre-recorded image and the live performance!
