I’ll build a self-contained lamp with animated wax, a desk scene, and an on/off switch, then check the layout and animation performance.

I’m taking it in a warm, quiet direction: a brushed metal lamp, glowing amber wax, and a walnut desk. The wax will use temperature-driven motion and fluid surfaces that join and separate, with the glow fading and the wax settling when you switch it off.

The lamp and controls are built, including three wax colors and a gradual cool-down. I’m checking the animation and phone layout now. The Linux test box isn’t reachable from this workspace, so I’m using a lightweight local browser check.

The controls and offline checks pass. A longer simulation caught a motion issue: the wax could drift toward the middle and stop circulating. I’m adjusting heat exchange at the base and top so the rise-and-fall cycle keeps going.

The revised wax keeps circulating in a six-minute simulation, settles after power-off, and rises again when reheated. I also enlarged the color controls for touch and kept rendering confined to the glass. Browser launch is blocked here, so I can’t measure live frame rate.
