So you like net art. And you wish you could "collect" it. But how does one go about purchasing a slippery, non-physical work of art, even by a recognized artist who works with pixels and programs? Check out Art Cart. At this site, you can get a collector's edition of Teo Spiller's "Trash Can" (pictured) along with a print, or have Valery Grancher paint a screen shot of a web site. The shopping's online of course...it's fun to browse, and a work of conceptual net art in itself.
