Creative Time, the public arts organization that brought Doug Aitken's Sleepwalkers to MoMA this winter, celebrates its 33^rd Anniversary all month long. Events featuring an international cast of artists, musicians, and performers will continue around the boroughs, and the organization will also move into its new headquarters in the East Fourth Street Cultural District.

On Saturday night from 4:00 to 7:00 pm at Printed Matter and 192 Books in Chelsea, the culture provocateur will launch Creative Time: The Book. And no ordinary book is this. The design firm karlssonwilker inc created its covers through a site specific public art project all its own.

Hjalti Karlsson and Jan Wilker programmed a suite of machines housed in a truck with clear Plexiglas sides, and recorded all kinds of data: temperature, wind, humidity, local colors, sounds and voices -- at locations where signature Creative Time projects had occurred. The data from each site was instantaneously transcribed into abstract shapes and patterns and printed on the spot, ultimately creating the 5,000 covers for the edition as the truck drifted through the city.

The book and the month of events ahead celebrate the 1300 artists and more than 300 public art projects that energized the city over the past three decades. From large-scale events such as Art on the Beach, Art in the Anchorage, and Tribute in Light, to intimate projects that gave emerging artists a voice, Creative Time has provided inspiration to experience the city in new ways.
