french design aissa logerot developed 'halo' an LED light spray.
Now, sweatshoppe has taken this LED technology to the streets on a different level.
the collective made up of video artist bruno levy and blake shaw who are also multimedia performers, use video mapping techniques as a means of video painting onto walls through the use of a paint roller. the only catch is, the paint roller doesn't actually paint anything onto the wall. instead it is made from green LEDs which work in conjunction with a camera next to a projector which is programmed with software that tracks its movements. the software then outputs the X-Y position of the roller projecting a textured video image of the strokes the duo are drawing on a wall. this interactive technology allows them to explore the relationship between video, mark making and architecture.
