Thanks! I've been planning on writing something about it but just never found the time. The shader is actually quite simple, although the implementation is pretty tricky (need a lot of hacks to get it working in Unity). All it's doing is lighting each tile individually. It's a throwback to the per-tile lighting of ascii roguelikes (http://osx.iusethis.com/screenshot/osx/brogue.png http://osx.iusethis.com/screenshot/osx/brogue.png). So each square chunk on the wall gets a single amount of light and color evenly distributed on it. That's it. Also, there are shadows on top of them. The props (torch and statue) have a banded light shader on them. It's just standard diffuse lighting but clamped to a certain set of values.
