An anonymous reader writes "CNET just published an article about a new challenge to photograph 5 target individuals in 5 different cities on March 31st. The TAG challenge will pay the winner $5k. Target mobility means this will be much harder than the DARPA Red Balloon Challenge which was won by MIT. From the article: 'On March 31, mug shots of five "suspects" will be published, and it'll be game on in a global hunt for "jewel thieves" in Bratislava, Slovakia; Stockholm; London; Washington, D.C.; and New York City, each of whom will spend 12 hours that day in public areas. The first team to upload photographs of each of the five by noon eastern time on April 1 will win the competition--and with it, a ton of international glory.'"
