Pablo (venomgfx) has made an interesting 10 minute video demonstrating a few different ways of using nodes and some GLSL features for real time game effects.
It features a new way of creating mist, plus some other cool effects like leaves becoming invisible as the camera gets a certain distance away.

“The thing was that Mist option is still not supported in GLSL, how can I work around this?, Nodes! the great “Camera Data†is an input node that let you use information from the camera view to play with, such as the View Vector, View Z Depth, and View Distance (which is the one i’m using in this video). After playing for a while, I found out that this method was much more better than the boring Mist!”
You can read more about the video, and watch it on this page of the Apricot blog.
