#490Spectrum Gate Sequence

A corridor of glass gates lined up in a shrinking run, and a single white beam fired down the middle. Every pane refracts each wavelength by a slightly different angle, so the beam leaves the first gate as a barely-split ribbon, the second as a visible fan, and by the last it has torn open into a full rainbow splay — Snell’s law compounded five times over. The gates breathe, their refractive power swelling and relaxing so the whole fan slowly flexes, and a bright flash burns at every point where a ray pierces a pane. Hover to raise or drop the beam and tilt its entry, scroll to crank the dispersion, and press to overdrive the beam until the splay saturates.
