Yep... these anaglyphs are good fun... it would be good to have a short cut, but unless there is a way to do this in one render (I don't think there is). There are apps that do the anaglyph part, but that's the easiest and quickest bit, so it's not much help. You could always run to TG2s together rendering the 2 shots simultaneously, but this would be more feasible when TG2 has been optimised.
