Figure: Brownian motion illustrated by an animation
Caption: "This is a simulation of the Brownian motion of 5 particles (yellow) that collides with a large set of 800 particles leaving 5 blue trails of random walk motion with one yellow particle with a red velocity vector represented."
This animation is NOT a photon case, but it gives you the right idea of how a photon does a random walk scattering its way through a gas of atoms and/or molecules.
