A candy-colored 3D run, made in one early Sonnet 5.5 chat

A white, smiling blob sits on a pedestal in a grey 3D world of spheres and pillars. The world turns pink, yellow and green, a “GO!!” countdown appears, and the character races across checkerboard floors, cut between labelled camera angles. The creator writes that it came from a single Sonnet 5.5 chat session during early rollout.
Anthropic says Sonnet 5.5 has a sharp eye for design. A playful, coherent motion piece from a chat window is one early sign of that—far from proof, but a useful test idea for anyone who makes short social videos or game trailers.
We do not know the prompt, how many attempts it took, how the video was rendered or whether it was edited afterwards. It came from a pre-release rollout, which may differ from the model you use today.
