A quick google search tells me that OpenSCAD doesn’t have a random number generator.  That’s a bit of a bummer.  I was just thinking how cool it would be to have an OpenSCAD file that would give you little variations on itself every time you generated an STL.  I’m thinking snowflakes, giant fingerprints, and other things that have a little bit of chance and chaos built in.

Or, perhaps some kind of Mad Libs-esque system where you tell it to create an alien or monster figure and you get a random number of eyes, heads, noses, arms, legs, and tails.

Now, I figure with CloudSCAD it wouldn’t be terribly difficult to add a little bit of javascript that can include a random number with given parameters…  So, it’s at least possible.
