A major international show of post-internet, virtual, digital (or however you want to # it) art is opening this weekend at the Fridericianum in Kassel. To those who have experienced the long journey to the banks of the Fulda for Documenta and feel that it is best undertaken just once every five years, we shall say only this: Speculations on Anonymous Materials promises to be worth devoting some long hours to Deutsche Bahn. With a press release introduced by a sublime block of hashtags and a roster that includes some of Rhizome's favorite artists, the exhibition tackles the #processbased #visuallyreflective #corporeal and #de-subjectified positions navigated by artists as they respond to technological change.
