Arpeggio Shapes turns sound into living light, Drag and drop any song (or play the built-in synth arpeggiator) and a glowing 3D form responds instantly, filaments spawn on melodic onsets, shockwaves ripple from kicks, hi-hats leave a shimmer, and the colour follows the harmony while flaring on every beat. Morph between six symmetriesm, Ribbon, Vessel, Mandala, Twin Ribbons, Helix and Lattice, on a pure-black canvas, with every parameter (shape, glow, motion, density) a live control you can tune while it plays. Scrub the waveform to find the perfect moment, then export crisp PNGs or drop into fullscreen wallpaper mode.
