Flick Pixels - Wallpaper for the Internet of Things

The aim of this project was to develop 'wallpaper for the Internet of Things'. Initially it seemed unlikely that there could be a simple and reliable solution to the problem, but a gradual process of evolution created a surprisingly elegant and effective device (patent pending). Besides opening up new creative possibilities for crafts, aesthetics, and customisation, the resulting technology is interesting in two engineering respects - it does not use conventional discrete electromagnets to move the pixels, and it achieves complex pixel movements without a complex control system.
