Normalmaps everywhere/2

First followup to this: http://c0de517e.blogspot.com/2012/02/normalmaps-everywhere.html

Nothing smart really, it's just a small Mathematica playground I made to visualize and experiment with normalmaps, mipmaps and phong, I'm posting it in case you want to play too!

Just to be clear, this is something to have fun and experiment, of course if all I wanted to do was to fit Phong (or any other rotation-invariant BRDF or part of them) I could have done it better in many other ways (first of all, by considering a single parameter that is the dot between the normal and the reflection vector/halfvector instead of working on the hemisphere). Hopefully I'll have something more "serious" coming out on the topic soo.. eventually :)
