changed: - some brief details about FPS: I bring computer, sensors and speakers. Necessary are additionaly videoprojector and a place to project to, either a white wall or a silkscreen. Measurements are variable but the sensor arrangement on the floor takes 2m x 1.20m and needs to be in front of the projection. Projector needs a reasonable distance to the projection surface and best idea would be to hang it above the people so they didn't interrupt the picture as easily. Additionally some installing material like Gaffatape for fixing cables are necessary. Setuptime should be within 2 hours max. The setup takes 3 power sockets, for Computer, Speakers and Projector.
