Miniature meditations on the imagery I notice as my life moves me around my country and the world.

Blue and yellow food coloring in water
In water, of course, food coloring diffuses much more quickly. I was surprised, however, to see how complex and uneven the diffusion can be. Here we see a drop of blue food coloring apparently following a hidden current in the upper layer of the otherwise still water, "dripping" down to the bottom in swirling pattern of turbulence.
