Johannes Grenzfurthner of monochrom, whose work we've featured many times on Boing Boing tv, reminds us that their annual "Arse Elektronika" conference is now under way. The name is a pun on the esteemed Ars Electronica festival; that one's venerable, this one's more venereal. Topics are sexually explicit in nature, but presented with internet-indigenous humor and wit. Arse Elektronika, "Critical Perspectives on Sexuality and Pornography in Science and Social Fiction," continues through Sunday in San Francisco. A very special congrats from BB to both Johannes and Evelyn, also of monochrom, who recently wed.
