Code-made satisfying videos / satisfying-physics

This skill was made by @DDJCXX, inspired by the Instagram account NexusBox Lab. He breaks down that account's satisfying video: more and more balls fill a circle, then burst out. The author judges it to be a physics simulation written in code, and has Claude write a matching version from scratch, with both the balls and the collision sounds generated in code. He released it as the free skill satisfying-physics, which works in Claude Code and Codex.

The author also says that Instagram account has about 19 posts and about 40,000 followers, that one video has about 36.28 million views, that 25 TikTok posts total about 52.92 million views, and that a 45-second video takes a little over a minute to render on a computer. Those view, follower, and timing figures are the author's claims and have not been verified.
