Synesthesia Synth
An experimental audio-visual instrument that allows users to sculpt evolving spatial audio by manipulating floating capsules. Position, rotation, and pulse changes affect tone, texture, and synchronized particle generation. It's a visual synthesizer, not a game.

Synthaestesia is a free experimental audio-visual instrument. Three capsules float in space. Every contraction produces sound. Move them, rotate them, reshape their pulse — and sculpt evolving spatial audio. Position changes tone. Rotation alters texture. Delay generates synchronized particles. This is not a game. It’s a spatial synth you can see.
