Nature may be analog, but humans increasingly strive to digitize everything in the name of saving time and space and furthering artistic endeavors. For the next two days, the College of Fine Arts and the Center for Consciousness Studies present the Fourth Annual Digital Arts Symposium, Neural Net(Work). Carol Flax, of the art department, and Lucy Petrovich, of the media arts department, are the co-chairpersons of the event, which aims to offer the Southwest the opportunity to meet with digital arts theorists and artists from around the world to better understand its role in society. Locations vary, so call Lucy Petrovich at 621-9966 or e-mail her at lucy@u.arizona.edu to find out what happens. http://www.arts.arizona.edu/digitalarts/symposium.
