These tapestries look familiar, because most computer users have had the frightening moment when a memory glitch causes the screen to fragment like this. Phillip Stearns uses leftover raw binary code (regularly purged from RAM, not needed for anything) to create his series Fragmented Memory. I really like that they are based on actual data even though they appear to be random patterns.

Every moment you use your computer, millions of 1s and 0s feed through the circuitry. Some are saved onto your hard drive, of course, but most are cached temporarily, routinely and permanently purged from RAM as more pressing information takes its place. The information dissolves in digital ether.
