"Create a pixel-art audio-reactive lighting effect using only vivid purple blocks against pure black. Keep the surface completely black and unlit whenever there is no audio. When sound is detected, make chunky square pixels pop into existence sharply in sync with the beat, forming scattered clusters and short stepped columns that rise, fall, and shift across the keyboard, mouse, LED strip, or desk surface. Use deep violet, electric purple, and bright magenta highlights, with stronger audio producing more blocks, taller formations, and denser patterns. Keep the motion crisp, snappy, and rhythm-driven, with blocks disappearing quickly after each sound rather than flowing continuously." — the prompt that generated this GLSL effect.
