Painting with light. When darkness comes it will be the right time for ghtpainting. Flashing lights in different colors and different movements. And with long time exposure and wide angle lens at the camera. The lens got a very different impression about the light and the movement like human eyes. The camerasensor can see the movement of light with lines and stripes. It is an other impression of light to see the light like a camera.
With the backframe system at the backside it is easy to hang.
