It's an 80 mm drop floating in zero gravity. You can poke it, pull it, cut through it with your hand, switch it from water to mercury, or pour it into a cube, an impossible triangle or a letter A. I didn't write a single line of code. Claude Opus 5.5 built the whole thing in Claude Code from my prompts. It's about 2,200 lines, all in one HTML file. \*\*How I built it\*\* I started with just the sphere, a material slider (water to mercury) and an influence slider. Once I was happy with that, I asked it to add the other shapes, then more sliders. After that I worked on the ripples and the physics to make it feel more real. The sound came last. \*\*What's under the hood\*\* (as Claude explained it to me) \- No fluid simulation and no 3D mesh. The drop's surface is about 150 wave shapes added together (spherical harmonics), and each one wobbles at its real frequency for a drop this size (Rayleigh modes). For water, the main wobble is 0.48 Hz, which matches the textbook value. \-…
