Show HN: A simple 2D fluid and gravity simulation with WASM and WebGL

The little particles will gravitate to your cursor (or touch location), and can even enter stable orbits if the conditions are right!

Mainly an excuse for me to experiment with wasm and WebGL, but it makes for a surprisingly good fidget toy.

This is really neat. I bet if you made the blobs follow a target point that moved around randomly it could make a good screensaver animation.

This is great! If you're looking for ideas on how to extend it, I'd love to be able to play with some of the parameters, or have presets to pick from. At some point I tried spinning it like a pizza dough but obviously these are way too liquid for that
