I am working on the software right now for a system that drives an single-row LED light strip mounted on the side of a car (e.g. right now the "data assembler" that solves all the symbolic references to store data structures in AVR8 program memory)<p>I'm expecting to attach it to the car in spring when the weather is better and I feel like messing around with adhesives.<p>I haven't seen it done before but I think that the ideal viewer would see my car light up like one of the holographic police cars from "Psycho-Pass".<p>---<p>I've thought about putting a bunch of light strips together in the back of the car so I can have a sign for tailgaters (e.g. show a dot matrix animation of the hatchback opening and some barrels coming out); that one is a lot more trouble because I'm not sure if I can make it so I can see out the back when I'm driving. Maybe putting a cluster of cameras on the roof would let me see out back OK but I don't know if the police would agree.
