I’ll build a self-contained lamp with animated wax, a warm glow, and a working power switch, then check the layout and animation for phone screens.

I’m shaping this as a quiet, warm desk scene with a glass lamp and brushed metal base. The wax will use temperature-driven motion and a blended surface so blobs join and separate smoothly; the controls will include power, color, and flow speed.

The lamp and controls are in place, including four color moods and gradual cooling when switched off. I’m checking the wax cycle and compact layouts now. The animation uses a small GPU-rendered canvas, with a fallback for browsers where WebGL is unavailable.

A longer simulation caught an issue: the wax eventually hovered at one temperature. I’m adjusting the heating and cooling zones so it keeps circulating, and tightening the layout for short phone screens.

The wax now keeps circulating through a ten-minute simulation, with repeated merges and splits. Switching it off settles the wax at the base, and switching it back on restarts the flow. I’ve also added layouts for smaller phones and landscape; I’m finishing the file checks.

Created [index.html]([workspace]/index.html) with a glowing glass lamp, thermal wax motion, smooth merging/splitting, power switch, four colors, and flow control. Fully offline with phone layouts.

Physics and controls verified. Optimized for 60 fps; browser FPS remains unmeasured.
