To paraphrase my old Soviet physics professor:

What separates US and Soviet education systems is that in the former, they try to polish everyone into a diamond, while in the latter they sift through the sand to find the nuggets of gold with maximum efficiency.

Love it. I'll be using this on a weekly basis in my art practice.

Let me know if you ever create an API endpoint.

Show HN: Elliptica – Make Art with Elliptic Boundary Value Problems

During my PhD in theoretical physics I spent quite a bit of time working on elliptic boundary value problems. I realized they are powerful generators of satisfying spatial patterns from relatively low dimensional input (boundary shapes and conditions). Combined with that I came across line integral convolution (LIC) which can produce incredibly beautiful visualizations of vector fields with...
