I've been experimenting with the math function, and having a bit of success, which doesn't particularly mean anything at this point. More specifically, I've been looking at the function defined for creating islands and, in turn, trying to figure out if there is a way to create craters along the same line, i.e. with that random shape rather than being perfectly (or near perfectly) round and with an increasing slope steepness towards the rim. I've wracked my brain on this, but, sad to say, I'm not much of the programming type (save for a little html and javascript), so if anyone has a clue how I might go about this, it would be great.
