That was fun.
Do you know of any good 2D smoothing algorithms? I implemented the
basic algorithm, but when I added the matrices together I got cross
hatch lines at the "harmonic" boundaries. I tried offsetting the
overlaps, as well as waiting to smooth the noise until later in the
process, but neither idea worked.

Were you going to build clouds as pictures and add them via
AddShapePictureWithMask? If so, I'd try looking up "perlin noise" on
your favorite search engine.
In fact, here's a readable Perlin noise article that not only has
RB-ish
code in it, but also links to a related real-time clouds article:
