My Berliner friend Franz John is in town this week setting up his installation Turing Tables at the Exploratorium. The piece, developed in collaboration wih Ed Osborn & brsma, uses live data from global seismics events to create sound & image. This piece is as much about human perception and digital interconnectivity as it is about techtonic events. Turing Tables opened last night & will run through June 18th.

Franz is an interesting artist who often works with the technologies of reproduction: photo-copying the entire inside of a gallery, scanning the sky, turning military bunkers into cameras-obsurae etc. Take a look at his projects at: www.f-john.de

And also his cd-rom project which simultaneously documents the dismantling of the Berlin Wall and transforms that experience into something out of Tarkovsky's Stalker: www.i-n-t-e-r-z-o-n-e.de
