A number of artists that I follow have played with the idea of placing a set of hemispheres of decreasing scale inside of one another, and some of those have been pretty inspiring to me. Here's me giving that idea a shot, with a little bit of motion. The color scheme for the rims in the "Innocent" variant was borrowed from my design "Warm Wooden Toy".
