It's a really neat effect. Some games are just rendering in 3d and down scaling it, that doesn't look so good. This method probably takes a little more effort, but the result is 3d-esque but super clear/not jaggedy, certainly worth the effort. I definitely want to try and use this technique at some point. I did already have an idea of the process, but thanks for the link, it never hurts to see how other people approach the same problem. :)
