I wanted a light object that reacts to music in a way that feels organic, not like a gaming accessory. Something you'd put in a living room, not a man cave.
Built around an ESP32 microcontroller running WLED firmware, with addressable LEDs in a circular form. The diffusion layer creates a nebula effect — soft, layered, no visible diodes. Audio reactivity comes from a microphone module analyzing frequency bands in real time.
The landing page is live, the waitlist is open. Still iterating on the diffusion optics and the form factor before the first production run.
