With this project I focused on creating a dynamic drawing which mimics changing sunlight on spheres meant to represent planets. Each planet rotates around its own axis at a rate derived from its respective actual rotation speed and additional objects are set into motion around various planet axises. The sunlight projected onto the spheres is tracked by the position of the mouse to add another dynamic variable to the overall image.
