Three 3D Shorts, written as code by Claude Opus 5.5
The popular "What If ___ Disappeared For 5 Seconds?" format, made with no video model and no 3D artist: Claude Opus 5.5 (Claude Code on the regular Claude Pro plan, effort low, every tool off) wrote each animation as one three.js web page, timed to the voice. These are the real pages, running in your browser. Press Play for the voice, music and sound effects.
Windows, windshields, glasses, a fish tank, the glass fibre under the oceans, every lens.
2 prompts: the first version + one message with four notes.
Ears pop, every flame goes out, engines stall, snack bags puff up, the sky stays blue.
2 prompts: the first version + one note (the snack bags).
A real 3D human (MakeHuman, CC0) built by Opus's own Blender setup script, animated bone by bone.
4 prompts. Three object names in the file were corrected by us (marked VitoMind fix): our prompt had given Opus the wrong names.

On the Claude Pro plan the extra cost was $0; the last column is what Claude Code reports the same run would cost at API prices. The human: MakeHuman's free plugin for Blender (MPFB, GPL) and its CC0 system assets, put together by a setup script that Opus wrote and we ran.
