Tonight at 7 PM, artist and activist Patrick Lichty will discuss his work at Upgrade! Chicago—the local "node" of Upgrade! International, a network "united by art, technology, and a commitment to bridging cultural divides." Upgrade! Chicago meets every second Tuesday of the month at the Nightingale (1084 N. Milwaukee). Lichty's done animation for the anti-corporate pranksters the Yes Men and is currently a faculty member of Columbia College's Interactive Arts and Media Department.
