Island Generator
This is cool, thanks for posting. I especially like how there are several styles of coastlines.I'm really interested in algorithmic generation of topography, probably by first creating fractal stream networks (either from the coast/ low elevation boundary or from watersheds/drainage divides). I'm a geologist so most game-oriented topography generators look super unrealistic to me, but making stream networks and working from there would be helpful with quantitative landscape analysis and simulations.  Anyone heard of anything like this?  If nothing else, then some way of filling in a polygon with branch-like fractals?
