Brian Eno published his work 
77 Million Paintings.  It's a 
hardcover book
 plus DVD plus Flash web-site.  Supposedly Mac and PC compatible and could be an interesting way to 
burn kilowatts on your fancy flatpanel TV.  He's showing at a 
gallery in SFCA.
David Byrne also published his 
Microsoft Powerpoint-based artwork
Microsoft Powerpoint artwork (though not online).  He actually also does 
presentations in Powerpoint describing his artistic process.  He's a big proponent of 
Internet radio and, in a 
presentation at SWSX last year, said that he tended to download pirated music due to 
DRM content restrictions. Some of his other artwork is 
displayed here.
