this GIF by Kevin Bewersdorf, with a technical assist from Paul Slocum
The Umbrico jpeg says "large salon-style hanging of illegible photos that may or may not exist in real space." A sense of great density of visual information is conveyed without any associated meaning. In the Bewersdorf each component GIF is basically legible, despite this being a reduced GIF version of a high definition video that was shown in New York a couple of years ago. "Legible" in the sense that you can read off its individual parts--flame, fly, beating heart, eyeball, candy cane--as opposed to "blur, grey-green blur, slightly larger grey-green blur, etc."
