From the annals of ultra-modern
From the annals of ultra-modern art comes interior design for amateur pornography. Internet Sex Photos and Obscene Interiors both exhibit what's left of amuteur porn photos after editing out the nude human(s). It is interesting to focus on what usually goes unnoticed.
Also, in the vein of art media for the Internet age, I recommend the Ebay Conceptual Art Gallery and Screenshots: History as Video Game.
