PREVIEW As I write this, I'm eating one of those new giant Cheetos you know, the latest delectable Alice Waters heart attack, sheer processed junk food Armageddon, elephantiasis of the puffed balls? Yum. My point here is that there's no form of art that hasn't been deeply and irrevocably touched by technology, and also that I'm a little stoned. Pitched somewhere between Maker Faire and head trip, the three-day art.tech festival at the Lab explores the intersection of artistic exploration, experimental fabrication, and digital prestidigitation and includes performance, workshops, presentations, and interactive flights of fancy. Among the highlights: a Virtual Knitting demo that entwines physical and virtual space; a "relational presentation" of Anti-Pandora, a hand-made backpack that generates usable energy from walking or running, and Seek 'n Spell, an interactive iPhone game that's a cross between Scrabble and a scavenger hunt. Dang, my fingers just painted my keyboard neon orange.
ART.TECH Fri/4-Sun/6, various times, $12$20 daily, $36 for three-day pass. The Lab, 2948 16th St., 415-864-8855, www.thelab.org
