With this POV light painter, you can paint the town red or any other color that suits your fancy. The LightScythe is a 2-meter long POV tube made up of multi-color LED strips. POV stands for Persistence of Vision which describes how our eyes see motion blur when an object is moving quickly. In this case, it enables us to see a message written with light.
An image is loaded onto a laptop which converts it to serial data, then sends it to an Arduino which controls the lightbar. A camera is set for 10 to 15 seconds of exposure, during which time the user walks across the frame, painting the image to be caught by the camera.
