Dissipation, dissolution, changing states. It is easy to apply these concepts to something like water; much more difficult when considering emotion and family relationships.
"With Evaporation Leighton extends this theme, in which vapor and fog collude invisibly to suggest the ephemerality of childhood and youth, and by implication, life itself. Here a young boy, who in this brief film becomes a young man, is seen looking out a window toward the sea, then near a harbor, walking on a pier, then gazing from the rails of a small ship. A rush of liquid abstractly rushes over a fall, the shifting fractals of waves move mysteriously, a boat sets out from the mouth of a river into the hazy infinity beyond. The boy looks pensively from the deck of a boat, the water rushing swiftly by. And we return to the window which looks out upon the sea, now empty."
