The site is quite barebones, containing only a description of the "work of art" its name refers to, and a video embed to the right of the text. After clicking the embed's play button, the short, pornographic video begins. It shows a naked man (possibly middle-aged) in a bathroom, stretching his anus wide open while screaming in agony for about 24 seconds.
The video used to have a song in it, but the site said that it was removed for "artistic reasons", as it "detracted" from the video's supposed core message; thus, the site calls the video it presents as "Clown Song version 2.0". It is comparable to Goatse, even if not as graphically disturbing.
NOTE: The following shock site contains pornography!
