Particles, a door, an optional pillar. Helbing’s 1995 idea in miniature — not a Concordia drill.
Educational particle sketch. Not calibrated. Not Concordia operations.
Each dot wants the teal door, avoids walls and neighbors, and (if checked) slides around a gray pillar. Raise the count until the gap clogs. Toggle the pillar and reset. A pillar splitting a pressure arch is a published pedestrian-dynamics result from Helbing-style social-force work (1995 onward); this canvas is a cartoon of it, not a code-compliant egress study.

If your browser asks for reduced motion, Play stays off until you press it. The sketch never leaves this page. Nothing is stored. Concordia does not run this as a drill, a HUD, or a Caregiver panel.
No bodies have mass in kilograms. No doorway matches a building code. No family groups, no smoke, no floor lights, no bulkheads. The status line counts cartoon exits, not survivors. If you need the civic timeline or named events, that is History, and it does not live in this canvas.

Dots are particles with a desired velocity toward the door, plus repulsion from walls, neighbors, and an optional pillar. Raising density or removing the pillar often builds a pressure arch at the gap — a published result in pedestrian dynamics, not a recipe for Concordia bulkheads. Prefer reduced motion?
