Re: Is this list still alive?

What you have described there is the algorithm for generating fractal plasma
(there are 2 types of plasma effects, fractal and sine/cosine)

As regards o the hex-map thing, why not take the average height of a set of
points in the generated map, and use those as the height of your hexagon?
This probably isn't the best method of doing it, but it is a quick and nasty
way...
