A lava lamp test
Author’s claim: Claude Fable 5.5 · model not released · not verified by us
About the post
A 30-second lava lamp animation, a common test for rendering fluid blobs in code. The author says it used maximum reasoning and looks much more refined than earlier attempts.

Our note
A single lava lamp on a dark backdrop, held in one fixed front view for the whole 30 seconds: a silver cap and a flared silver base around a tapered clear glass, with orange wax glowing where it pools at the bottom. At times a column of wax reaches up out of that pool, while separate rounded blobs float higher up the glass, and the lamp throws a warm circle of light onto a glossy floor. There is no text, no interface and no sound. The maximum-reasoning setting and the comparison with earlier attempts are the author's account; no prompt was shared.
