Open-source stims • Quick to try • No accounts

Feel-first visuals that breathe with your audio.

Explore audio, color, and motion without setup. Every stim opens fast, responds to mic and touch, and comes with sensible defaults that keep you in flow. When you launch a toy, we’ll ask for microphone access so visuals can react to your sound.

New highlight cards pair atmospheric gradients with clear descriptions so you can pick a palette that matches your mood.

Glassy borders, subtle glow, and rounded corners that feel tactile.

Callouts explain how to start with microphone input, demos, or device motion without ever feeling technical.
