A single-file interactive 3D plush octopus built with native WebGPU. The fur has a sheen and strands, and you can drag the arms to stretch them, use a finger to make the arms wrap around it, comb the fur to change its direction, and shake or toss the toy. It comes with an editorial-style interface and live physics readouts. The video is a screen recording of a side-by-side comparison with GPT-6.1 Sol on the same prompt, about 18 seconds long. Suited to physics interaction demos and technical showcase short videos for social media.
