The robot, AKA pablo.wright is a mail artist who has been working in the medium since February 2003. In 2004 the robot/pablo.wright started an overtly political (and decidedly anti-Bush) mail art campaign. (Unfortunately, it did not seem to sway the outcome of the 2004 U.S. Presidential election.) The project has grown from there and consists, mainly of brief screeds on the "b" side of original linoleum block prints.
The robot/pablo.wright has very little formal art training (and it shows). The artist also works with acrylics, opaque water colors, and occasional stencil art graffiti (don't try this at home) and is active in trading Artist Trading Cards (ATC's).
