orb scan

A biometric unlock screen on a near-black 1080 × 1080 stage, built round one glowing orb like an iris. At rest it reads Pupil Key · Look at the orb: the orb's pupil breathes, magenta fibres flicker out of its rim and its gaze wanders. A face rises below it as a depth map of glowing dots, the deeper ones bigger and brighter, and the orb's pupil stops down as it looks at it. A scan line sweeps the face top to bottom and the gaze follows it (Scanning · Hold still). The first face is a stranger: the orb flares, its pupil slams shut, red veins spread through it and it shakes its head, Not you · Access denied, while the dots tremble, turn red and drop away one by one. A second face is scanned the same way and this time the orb turns calm blue, looks up at you and opens wide, the dots pulse white-blue in waves, and the line reads Welcome back, Mira · Unlocked, before it all settles back to the idle orb. There are no photos and no real faces: the face is an abstract shape of dots, and the orb, its iris, aperture blades, glint and halo are one WebGL fragment shader. The status line is drawn on a canvas in Geist with a soft cross-fade. It loops every 14 seconds; every frame is a pure function of time, with window.__render(t), ?rec and __MANUAL for frame-exact video export, Space or R restarts it, and reduced motion shows one still. The idle label, the owner's name, the beats and both faces are a few lines to change. The font is local, so it runs offline.
