I always wonder what these little creatures are saying and sharing amongst themselves as they cluster, and flow like liquid atoms in some ephemeral molecule across the surfaces to which they cling.
Are they like the two vultures in the Jungle Book?
Are they in a bull session, divying-up territory that their later travels are more rewarding?
Segments of code, soft-wear, a Program to which they each contribute, down, load lightened?
Whatever your motive, motile; still, I am glad you allowed me to get close, and see.
