This is a really cool way to make relativity feel intuitive. I’ve always found that the equations are much easier to understand once you have a concrete mental picture of what an observer would actually see.
I’m curious how you’re handling the visual distinction between time dilation/length contraction and the actual light-travel-time effects an observer would see. That seems like it could get surprisingly unintuitive once the scaled-down speed of light gets close to the objects’ velocities.
