Most of the experiments I make these days have something to do with either fractals or Box2D, so I had this brilliant thought on the weekend ... how about fractal trees in Box2D! Ok, maybe it's not that brilliant.
It's a pretty straightforward demo right now, but there's something cool about seeing physics-ey trees swaying realistically (as there is with most stuff in physics engines).
If anyone's interested in the source I'll release it at some point. Hopefully it'll end up being used as part of a game that I have in mind, look out for more updates :)
