  3. The Secret Lives of Numbers
    A Java applet histogram exploring the relative popularity and cultural associations of every integer between 0 and one million. Numbers such as 212, 486, 911, 1040, 1492, 1776, 68040, and 90210, for example, occur more frequently than their neighbors because they are used to denominate the phone numbers, tax forms, computer chips, famous dates, or television programs. The authors describe their dataset as "a numeric snapshot of the collective consciousness.... to provoke awareness of one's own numeric manifestations." The Secret Lives of Numbers is a commission of New Radio and Performing Arts, Inc., for its Turbulence.org web site, developed with support from the Greenwall Foundation, and conceived by Golan Levin at Interval Research Corporation. more>>
