A space for attention
A quiet companion for whatever has your attention.
Let the light move with you.
YOUR PACE. YOUR SPACE.
Wear your device. Let the light respond.

Just exploring?
Ambient light works without a wearable. Demo signals are generated examples, never measurements.
Give this moment an ending, if you’d like. Your space stays open when the time is up.
No timer is running until you choose one.
A few small ways to settle in.
Luminous layers of color. Turn off for a softer field.
Settle into the light. Hide the welcome text.
Keep the stars still. Let size and color carry changes.
Pause the visual whenever you like.
4 seconds in, 6 seconds out. Optional pacing.
An experimental estimate of physiological activation relative to your own reference.
Keep your wearable on while a fixed two-minute reference is gathered. It stays fixed until you reset it.
The original multivariate architecture combines cardiac, respiratory, EEG, and covariance changes, with temporal-pattern modifiers. Zero is the reference origin; higher values reflect a stronger response under those terms. Covariance distance can respond to changes in either direction. The active terms and their weights are shown below.
A local JSON download of feature frames and this model's provenance. Open it in Signal Lab to replay the same calculation.
A wider, brighter, warmer nebula means a higher estimate. The faint dotted orbit marks the reference origin of zero. The cloud expands beyond that orbit as the index rises; drifting stars are decorative. Work shows a slowly orbiting galaxy. Rest softens it into a cloud, with an optional separate breathing ring: 4 seconds in, 6 seconds out.
Keep this space beside your work, or let it fill the screen while you rest. You don’t have to do anything to use it.
