A Mandelbox, or so the web tells me, is a box-like fractal object that shares several properties with the well known Mandelbrot set and is a map of continuous, shape-preserving Julia sets. It also makes for one trippy piece of animation.
I think that if it were located in a temperature-moderate zero-gee environment with breathable air, a Mandelbox would make for one terrific city. We should start work on one ASAP.
And I am moved to editorialize . . .
You young people and your computers! Slackers, the lot of you. Back in my day, if we wanted to see something like this, we had to imagine it ourselves. Using drugs.
