disk (021), three.js HTML animation I was walking home and thought I saw the moon. I stood there looking at it — the right size, the right height in the sky, that familiar pale disc. Then I realized it was a parabolic antenna on the roof of a building, facing toward me. Each piece is a disc that breathes slowly between convex and concave. The seed determines its character — how fast it moves, how deep it goes, where the light catches it, where it sits in the sky. Some will look like a full moon. Some will look like a dish.
