Light Graffiti: The LED Spraypaint Can
the LED light can change colors and brightness on the fly and while it's powered by an internal battery that can be charged by shaking of the can.
"Graffiti artists can conserve their own gesture they have with an aerosol spray. It is possible to change the color and the brightness of the led to change the graffiti's styles. If the light doesn't have enough battery, the user must shake it to have energy again."
Sure you could do the same thing with any LED, but I like the can form factor. Plus, I like shaking things. So, what should I spray first? I'm leaning towards A WAY TO YOUR HEART. Then, once you're mine, a dinosaur eating an airplane.
