Been a while since I did one of these.

Can you control the sizes? I like the effect, would like to see variation in sizes, though. Cool stuff, Lyle!

Thanks for the comments, Mahvin. Since it's based on a masked pattern (click here for pattern) followed my lylejk stencil to smooth out the edges before running G'MIC's Gradient Norm for the loops themselves, the only thing you can do is scale the pattern.
