Developers post animations they say Opus 5.5 drew in code
One made a 40-second explainer on how browsers work, another a 3-minute history of AI from about 7,400 lines of React and TypeScript.
Eric Buess posted a thread on Thursday evening collecting animations and short films that he said Claude Opus 5.5 produced by writing code rather than by generating pixels. He credited each maker by name, and his opening post had 840 likes and about 118,000 views when read on Friday morning.
Buess wrote that Opus 5.5 cannot generate an image or a video directly, and that it can write code that draws, animates and edits one. He said Alex Greensh has open-sourced Anidoodle, a skill for hand-drawn illustration and animation in deterministic code. Greensh says it works better with Opus 5.5.
Addy Osmani made a 40-second piece on how browsers work, with every frame drawn in JavaScript, according to the thread. The account kimmonismus made a three-minute history of AI in about an hour. It used roughly 7,400 lines of React and TypeScript in Remotion. The thread lists an open-source text-to-speech voice and a score synthesised in Python.
The thread also carries a proton collision built in Blender by the account superalesha, with particle tracks it said were calculated from the detector's real magnetic field. Another entry, by LCSlates, is an 80-second film in a single HTML file. The thread said it uses WebGL2 and plain JavaScript, with no libraries or asset files.
Gregor Zunic, who posts as gregpr07, gave the model 13 takes of himself saying one sentence. He said it read every transcript and compared the top three frame by frame. It then cut the clean one, graded it and added captions, in two minutes for 90 cents. None of the work has been checked outside the thread.
