I've worked in real-world media, oils, pastels, etc. There are programs available for a 'puter, that can do a pretty good job of mimicing traditional media. I like stretching the envelope with "so-called" computer art. It's just as demanding, maybe more(think of all the functions, etc. you need to master). When I see some of the work done just here, alone, there is no doubt that real art and artists exist in the computer world, as well. The average guy on the street doesn't become an artist with a graphics program any more than a chimp with a brush and paints becomes a Michaelangelo. Art is much more complex and etherial than that.
