Claude Opus 5.5 Is Actually Insane

I went through the Claude Opus 5.5 release and independent evaluations, then looked at 16 projects people built with it: coded animation, interactive websites, real-time 3D, longer agent workflows, and music. I also show three projects I made: a premium tennis brand site, a 15-second motion showreel, and a track built with code. The projects belong to their original creators. Some combine Opus with other tools, including ElevenLabs, and existing music. Their posts and the research sources are linked below.
