Not a site.
A haven with
a heartbeat.

Pulsehaven is what loads when the machine gets tired and the water takes over. Every card is a ganglion, every hover is a fingertip, every click is a pacemaker tick. Dive in—it will pulse back.

Reefs that conduct

RF-01

Algaeclock

Photosynthetic timer. Glows on a 24-minute day. Tells you nothing useful, beautifully.

540 lux · breathing
RF-02

Synapseshoal

A school of nodes firing in loose unison. No brain, just agreement. Scroll and they shift phase.

3.2 Hz · phase drift
RF-03

Tidememory

Stores the last high water in a jelly layer. Recalls it when you hover. Forgets by morning.

+0.4m · retained
RF-04

Heartanemone

Beats on its own rhythm until observed. Then it syncs to yours. Rude, but intimate.

62 bpm · coupling
RF-05

Causticveil

The water's own UI. Refracts every card beneath it into three wobbling ghosts.

2 layers · refractive
RF-06

Deeppace

The fallback oscillator. When everything else flatlines, this one keeps the lagoon from dying.

A tidal reading

On Living Interfaces

A page should not finish loading. It should keep loading—slowly, like a tide. The heart rate is the spinner. The algae is the skeleton.

We do not ship pixels. We ship phase. You press, it contracts, then relaxes into a slightly different shape. That is the only persistence.
