Maxwell's Demon

Interactions

Click the door in the wall to wedge it open for six seconds: the hot and cold halves start to mix and the difference decays
Click a molecule to kick it: it shoots off fast, tinted red, and shares its energy through collisions
Click the imp to make it doze: its slack hand lets the door drift, so molecules pass at random
Idle: three acts cycle by themselves: free mixing, the demon sorting and writing bits, and the erasure that warms the brazier
