Blozzum Bitty is a studio for sound-reactive visual art. Build a composition from shapes, effects, and color, bind anything to your music, and watch it move, bloom, and breathe in time with every beat. It's the lightweight member of the Blozzum family — light on your battery and instantly playable on iPhone and iPad, while still giving you real creative control. HOW IT WORKS Start from a shape. Add a stack of mutation and effects to twist, warp, and stylize it. Finish with a final stage of touch ups. Then make it listen: different audio metrics (RMS, Frame Peak, Kick, Beat, etc.) can drive most any parameter in the paths, mutations, and effects — you decide what reacts to what. Use the mic for live input, or load an audio file and loop through it. EASY ON YOUR DEVICE Blozzum Bitty runs a streamlined, single-layer engine with a gentle frame-rate cap, so it stays cool and battery-friendly during long sessions.
