Though Andy's digital paintings are completed using the computer paint and touchscreen programs, they're still painted manually, so to speak. The touchscreen acts as canvass, the paint program provides the palette, and (for Andy) the tip of a plastic pen barrel or pen cap acts as paint brush. As he paints, he works his paint brush (pen barrel or pen cap tip) manually from side to side and from top to bottom of his canvass (touchscreen), much as he would on any traditional media painting. (Or is it from side to side and bottom to top? Or center-out? Or outside-in? Andy seems always to have a very definite strategy in his approach to his subject, and it seems sometimes rather complex to say the least.) Andy now works almost exclusively in the more traditional media, however-- chalks, watercolors, etc.
It might be worth noting that the quality of computer touchscreens varies quite
dramatically, expecially in respect to how accurately and sensitively a
touchscreen responds to the artist's "brush strokes" when it's in "paint" mode.
Andy uses an old touchscreen of exceptionally high quality in that
respect; the newer touchscreens available to him are quite nice,
but an individual with exceptional artistic talents needs a touchscreen of
exceptional quality, not a merely nice one.
