SIMULATED GLOW-IN-THE-DARK DISPLAY

Perfect Execution

This is a Processing sketch that simulates an interactive display made by scanning a row of UV LED pixels up and down a surface painted with strontium aluminate paint. The display plots pixel contrast from a live webcam feed, which emphasizes the edges of objects in the image. If the objects move during the scan, they will smear the image, which leads to interesting effects. The long decay time of the strontium aluiminate phosphor means that the outlines would persist on the display for hours as their brightness fades away. Static objects in the image would become progressively brighter.
