Well, true, that. I thought briefly of tori, but didn't immediately feel any torus love, no. But now that I think about it more... ooh, and you could have the 'sun' be a ring of fire that goes from inside the torus, down, stretches out to be larger than the torus, moves up, narrows again, and returns to the centre...Originally Posted by Cybren
(And a torus is intriguingly easy to map, because it can be unrolled to a flat surface...)
