if caffeinated, the particles become frenetic and zip around the growing shapes. are they constrained and go forever? or are they bound in the boxes that we all inevitably find ourselves.

time will tell, but i'm pretty sure there are constraints.

centered shapes can become a square or circle as desired. depending on the hash your background may be dithered or not, a strip, a pair of gradients, or flat.

the shapes can become frenetic as well. guessing it has something to do with coffee.
