Draw fading images on the sphere from within by using an ultra violet laser which is able to activate the photochromatic dye for short periods of time.

The project was done for and in collaboration with the Bloomfield Science Museum in Jerusalem that provided us with the hardware and photochromatic paint. It was created to serve as a science exhibit that demonstrates the properties of photochromatic dyes with basic svg drawings so keep in mind that more advanced projector capabilities might be missing from the code. The code is licensed with the MIT license so you are free to use the code for your own needs.
