Keyboard commands:

[SPACE] Stop and restart experiment. This will reset number of speed flows to something between 1 and 8.

[k/l] : increase/decrease number of particles in each speed flow class (in this first experiment, the distribution of particles is even among the speeds).

[a/s] : increase/decrease size of particles

[c] : toggles comet-tail behind the particles (direction cue!)
