In my search for unique display ideas I came up with this concept. It can be described as the fully magnetic equivalent of a kinetic sand art table (e.g. like this one). Below a magnetic field viewing film a small magnet is moved in 2D by PCB coils. In this way the magnet can draw patterns on the film like the ball bearing does on sand. The display can be used to draw patterns but because I am a big fan of unique clocks I also programmed it so that it can display the time.
