The microphone's FFT sculpted into an oblique glowing landscape: each frame's spectrum is written into a scrolling frequency×time history and rendered as a fake-perspective heightfield — low frequencies as big mountains near the viewer, highs as fine distant ridges, past audio receding toward a fogged horizon like sediment. Ridge lines glow, valleys stay dark. Click the tile (while focused) to grant the mic; until then a composed spectrum of moving harmonic humps and sparse high-frequency glitter plays like slow music.
