Features:
Efficient procedural sim of infinite star systems with planets and moons. Planets and moons orbit using Keplerian ellipsis system so they can pause when unloaded and jump to correct position for any input time when reloaded into view. LOD system for drawing and simulating. Shaders for gravitational forces. Dynamic grid with scale bar. 
Shaders for planet texture and clouds. Background starfield shader.

Each star system has a local clock. I was going to use this to add special and general relativity time dilation as well as length compression on camera movement but didn't get to it. Idea was farming game where you travel at relativistic speeds to do something somewhere else while much time passes on first planet and plants grow
