An interactive jelly-textured Lego-brick toy built with Three.js using the same detailed prompt given to both Claude Opus 5.5 and Gemini 4 Argon, comparing the jelly-like physics of each result.

Full prompt2,369 chars

Build a single self-contained HTML file: an interactive 3D toy called "Jelly Bricks" - translucent gummy candy bricks you can grab, stretch, stack into a tower and knock over. Use three.js (import from a CDN) and any lightweight physics library you like. Everything must run by opening the file in a browser.

LOOK
- Bricks are classic stud-on-top building bricks (2x1, 2x2, 3x2, 4x2) in red, orange, yellow, green and blue. No brand names or logos anywhere.
- Material must read as real gummy candy: glossy, translucent, light passing through, deeper colour where the brick is thicker, soft rounded edges and rounded studs. Use MeshPhysicalMaterial with transmission, thickness, attenuation colour, clearcoat, and an environment map for reflections.
- Soft shadows plus a faint coloured glow on the floor under each brick, tinted by its colour.
- Clean white background, slight slow camera drift so the scene feels alive.

JELLY BEHAVIOUR (most important)
- Grab a brick and it stretches toward the cursor before it lifts off, like pulling taffy. Release it and the stretch snaps back with a decaying wobble.
- A brick lagging behind the cursor tilts slightly in the direction it's moving.
- Every landing squashes the brick flat, then it springs back up with a few wobbles (spring-damper squash and shear, done in the vertex shader).
- Dropping a brick on the stack snaps it in place, and the whole tower sways like pudding: each brick's wobble shifts the bricks above it, so the top moves the most.
- Pulling a brick out of the middle of the tower collapses it: the bricks above tumble, bounce off the floor and each other, and scatter a little - lively, not explosive.

UI (minimal editorial style)
- Top left: small caps label "Nº 09 / SOFT GOODS", big serif italic title "Jelly / Bricks." with "Bricks." in red, and a one-line subtitle.
- Floating panel on the right: flavor colour swatches, a "Wobble" slider that controls jelly softness, live "Stack height" and "Bricks" counters, and a black "Pour more bricks" button that drops a handful of new bricks from above with random spin.
- Bottom left hint: "Grab to lift · Drop to snap · Space to wobble". Space shakes the tower.
- Custom round cursor that shrinks while holding a brick.

Start with one 4x2 brick in the centre as the tower base and about 9 bricks scattered around it. Keep it at 60fps on a laptop.
