"Twittering Machine" by Paul Klee (1922)

This painting (currently at the Museum of Modern Art in New York) depicts a strange contraption consisting of bird-creatures attached to a wavy-wire attached to a crank. You turn the crank, and the birds make noise ... a prophetic vision of an audio-producing computer.

pdx rune

The "pdx" moniker started out as my Space Invaders high score initials ("gamer tag"), meaning "peter drescher, his mark" (sorta). Later, computer systems I worked on in the 80's required three-letter logon IDs, so "pdx" seemed the logical identifier. Later, while in the circus, I designed the "pdx" rune, using straight lines only (as if carved in stone, like Viking, or Tolkien elvish, letters), and used it to stamp my musical equipment and other personal property. I continue to use the moniker as my online identifier, and email signature. On 8/2/06, to (literally) mark the occasion of my 50th birthday, I tattooed the symbol to my left shoulder.
