A couple of projects have occured to me that could use such a beast,
although they have (so far) been of the "neat, but not worth diverting
attention to now" variety. A few ...er.. random ideas:

An abstract art program that keeps a repetoire of objects, textures, 
lighting and view elements in separate INC files, and generates 
random pieces each time it's run.
An animation script running a variation on the Life Genesis game 
which randomly arranges the starting positions of the life pods (in 
this case blob components) in 3D space so each run is genuinely 
unique.
A POV-Ray file that generates a random figure from a Tarot
deck (or Norse rune cast, or I Ching, or magic 8-ball response,
or... well, you get the idea: plenty of variations) and renders it
along with a text object, or scroll or something expounding the 
meaning. For obvious reasons if it kept rendering the same 
cast/draw/hexagram each time, it would be self defeating. 

You *could* just manually reseed every time, but its just the 
principle of having it self contained. Again, it's all stuff to 
do when you're bored and don't have a main project or if you have 
a more powerful computer than you know what to do with <g>, but 
hey, it's a simple enough trick and it might come in handy 
sometimes.
