For the first time ever, magazine covers went interactive. Thanks to DynaColor^TM thermochromic offset inks from Chromatic Technologies, the cover of the January 2001 issue of WIRED Magazine was a heat-sensitive plaything, changing colors when held with a warm hand, rubbed or breathed on.

WIRED was pleased to be the first to use the idea on a major magazine cover. "It's been a very popular issue," said WIRED's Jay Dayrit, noting that they've had an unusual number of requests for extra copies. Both WIRED and CTI received many calls as a result of the issue, from ad agencies, designers, printers and others, wanting to know how they could do something similar with CTI's interactive inks.

WIRED made no mention in the issue of how the effect was accomplished, perhaps heightening the intrigue surrounding it, and causing some individuals to spend hours searching out the source of the interactive ink.
