A sacred-geometry mandala driven by your nervous system. Three live signals shape everything you see — colour, motion, sharpness, and the moment of gold.
Sustain coherence above 0.72 and full stillness for two seconds and the mandala locks — petals sharpen to their finest, the palette goes deep gold, a halo breathes around the edge. The lock holds as long as you hold it.
The bar in the HUD blends all three signals into one number. It rises when your heart is slow and variable and your body is still — the classic signature of a settled nervous system.
Nothing to do but be here. The geometry is the readout — let it show you where you are.
