The FrostHerbarium

An unkeepable garden grows on the cold side of the glass.

Press & hold the pane to breathe a clearing

Frost grows continuously from the sill. Hold Space, or press and hold anywhere on the pane, to melt a circular clearing. Release to let frost reclaim it. Press Enter, or tap quickly, to seed a new crystal colony.

Winter makes a forest

Water molecules wander the pane until one touches ice. Then chance becomes architecture: attachment, branching, a white geography that remembers every collision.

The simulation above follows the same bargain. Thousands of walkers drift across a lattice. A near neighbour invites them to stay. Temperature changes the odds and direction of that attachment, turning identical water into feather, spear, or blind sheet.

Collected from the north stairwell before the building woke. Every plate is a generated reconstruction from a custodian’s temperature log; none can be grown twice.

Breath study / temporary thaw

You lend the window
twelve seconds of spring.

Your palm warms the pixels; your held breath widens the clearing. Behind it: one amber lamp, the suggestion of a roof, snow still falling. Release, and the rim closes inward. The oldest crystals return first. The last bright aperture is no larger than a pin.

Custodian’s ledger / January 18

What the pane
remembered overnight

First whitening

A pale seam gathered where the sash leaks above the eastern hinge.

Branch event

Six trunks divided at once, each turning two degrees toward the colder jamb.

Breath interruption

A visitor made one warm moon. Diameter: 184 millimetres. Duration: brief.

Full reclamation

The moon vanished. A single drop remained on the sill like a specimen pin.

The collection closes at dawn

Nothing here survives
being warmed.

At 07:26 the sun reaches the east glass. The herbarium becomes water, and every label is wrong.
