In this screen saver you can see real thermodynamically gas model. Show each molecule in close space, you can see process of condensation and free Brawn-like moves.
Realized real physical model of move, collisions and reflection, its just like a 3D-pool. You can see by yourself process between hot and cold air under this virtual microscope.
In advanced mode hot molecule is red and cold is blue colorized, also hot is more fast then cold.
