OBSERVATION CHAMBER / MVP

Avalanche Sandpile

Drop grains until one threshold break sends an avalanche through the pile.

critical Operational

CRITICAL FIELD

Drop grains, start rain, or draw on the table. Bright cells are toppling now; pale traces show where previous cascades passed.

BUILDING

First observation Press DROP GRAIN or draw on the table. A quiet pile may suddenly break into a chain.

grains 0 / avalanche 0

OBS-000 / HEIGHT / 00:00

SYSTEM NOTE

Local limit, sudden chain.

A visual criticality model inspired by sandpile avalanches. Not a physics simulator.

OPERATION GUIDE

Build the threshold.

DROP GRAIN adds pressure at the center.
RANDOM RAIN spreads grains across the table.
SHAKE moves small instabilities sideways.
TRACE keeps a faint memory of previous cascades.

OBSERVATION POINTS

Watch where the chain releases.

Point Pile grows from one quiet center.
Ridge and Fault Line reveal how shape redirects collapse.
AVALANCHE and STABILITY lenses separate active topples from stored tension.

Use DROP, RAIN, SHAKE, and RESET to trigger avalanches.
Adjust threshold, dissipation, grain size, and drop rate from this panel.

OBSERVATION GUIDE

Touchpoints for Observation

Observe local height crossing a threshold, toppling, cascading, and leaving avalanche traces.

Drop grains, start random rain, shake the field, and compare Height, Avalanche, Stability, and Trace.
Quiet buildup matters because the next grain can trigger a wide cascade.
Trace view keeps the memory of recent collapses visible.

This is a visual criticality model inspired by sandpile avalanches, not a physics simulator.

Runs inside the browser with no upload and no registration.

SYSTEM NOTE

height(x, y) >= threshold -> topple -> neighbors + trace. Local overload becomes cascade.

OBSERVATION POLICY

This observation LAB runs in your browser. It does not upload images, pointer traces, or input.
