Recursive Random Triangular Subdivision

I've started getting into writing my blog on my lunch hour so I've had to come up with some quick and easy 30 minute experiments - I need the other 30 minutes to eat... Here is today's result (it follows along the lines of my circle packing experiment a while back). It works like this. One starts by drawing a triangle, then picks a random point within that triangle. These vertices are then used to draw more triangles, and the process is repeated recursively. At each stage the triangles are rendered with a level of transparency. This means more "visited" triangles will appear brighter thus forming a kind of network. Click the image below to launch the demo and find the source here.
