The "cancel" and "resume" buttons on tiled boxes locate the source of their design as standard pop-up messages on a Mac. But the text in each one—"You are being watched"—is new. It is a reminder of the perpetual surveillance on the web, where each user's data are subject to constant collection. Shaky animation and a dissonant, looped squeal intensify the message's urgency. The splash page has the speedy, sweaty-palmed feel typical of the work of Los Angeles-based artist Antonio Mendoza, whose web sites bear mottos like "the.web.on.crack." His art gives form to the dangers and fears associated with internet use.
