Someone asked me a question today that I couldn't really say a definite answer to... how to make the color shifting paint that you see on vehicles and sunglasses. I did a search and found this tutorial
http://www.danielbuck.net/old/index.php?page=paint_tut/painttut but figured I might as well ask here to see if there were any other suggestions on how to achieve this.

It's just a fresnel that blends between two types of colors. Very easy to do if you know some shaders.
And that thing on Daniel's site is even easier, that's just colored specular with noise as glossmap, my shader can do that in realtime.
Yep, pretty much that kind of paint exactly.
I don't really know much about shaders, I really should look into it more.
I'm checking out your video on cg tuts+ right now, thanks a ton, it seems extremely helpful.
