Few artists can resist the urge to sketch on a clean whiteboard. Sketching on a PDA has much of the same appeal. All of these images were created at 160 x 140 resolution on a Sony Clie Palm PDA with just a few shades of gray. I spent about two or three minutes on each sketch.
Working at such low-resolution with an imprecise art tool is liberating. There is no pain when a sketch turns out badly. That it is possible to capture a likeness this way still amazes me.
