A cheeky name in the light of Apple's Cover Flow, nevertheless please excuse the sudden link to my initial engagement with Fine art and Literature....... once upon a time I was completely absorbed in studying the works of Savador Dali, the images in those books used to keep my mind and body absorbed for hours at a time. This led me into reading Aldous Huxley's Doors to Perception and Herman Hesse's Glass Bead Game.
Similarly I think this young man's video of Food coloring being dropped into water, could help you find the faces I found in the cloud of Cover fLOw.
Although the soundtrack Recurring by Bonobo might be less of a concern if it weren't for the rather abrupt ending to an otherwise rather enlightening yet simple idea.
