In theory a perfect torus is it's own toral inverse, but the Paul Chang Klein bottle isn't that exactly. The see-through picture shows it is still a Klein...

It's a fun plot, but I don't understand how you got it to run. I had to change the range parameter of t from {t, 0, 1} to {t, 0.01, 1} to avoid a divide by...
