Black hole is a black hole and its accretion disk, drawn by shaders written in Go (package ui/shader) on the GPU: every pixel's ray of light is traced back through the hole's gravity, so the disk's far side shows above and below the shadow, the side turning toward the camera blazes brighter and bluer, and the stars behind smear into arcs around an Einstein ring.

Chart-streaming draws three rolling waveforms of 15,000 samples each, 1,000 new samples a second, reduced to a few points per pixel column.

Chat-glow is an assistant's window, lit as Apple Intelligence lights its own: while the assistant works, the window's edges glow in flowing colors, the field to write in glows in its ring, and "Thinking…" shimmers; the assistant's orb, a glass sphere of drifting light, quickens as it thinks.
