Very cool. I did something similar (but much less advanced) in math class where I generated something like a height map by "randomly" (I'd really just pick numbers that seemed good) assigning values to a grid and then subdividing the grid and linearly interpolating between points plus another "random" offset with a range that gets divided with each subdivision. It was a good way to pass time for someone who would rather have been playing dwarf fortress but only slightly understood the math behind perlin noise.
