Love the project, writing style and what is was made of (fpga, round lcd, Jupiter moons sim... so cool). But now I'm frustrated I can't see the display animation.
It updates in pretty close to realtime (ie the simulator timestep is extremely close to the actual wall clock time required to compute the next timestep), so “animation” isn’t really the right word. If you let it go for a few hours it leaves fun star trails though!
