The Crucible
Karel’s piano is the only heat source. Its moment-to-moment energy sets the temperature of a real Lennard-Jones gas — ~900 particles under genuine molecular dynamics. Quiet passages freeze matter into a hexagonal crystal; loud ones melt and vaporise it. Drag on the field to stir in heat by hand.
