Random convex polygons

This is a demonstration of the OpenSCAD code for generating random polygons as discussed in http://kitwallace.tumblr.com/post/176388478009/random-polygons.

Randomness has its own problems: The customiser regenerates the solid whenever a parameter changes (ok) but also on every move of the viewpoint (useful to see alternatives if a bit confusing). However it also regenerates when saving so you cannot choose a shape and save the same shape.

Also beware that for some settings of the para
