"A team from UC San Diego is using crowd-sourcing as a tool to solve the most complicated puzzle ever attempted, which involves piecing together roughly 10,000 pieces of different documents that have been shredded. (The challenge is designed to reveal new techniques for reconstructing destroyed documents, which are often confiscated by troops in war zones). The prize for solving this jigsaw puzzle is $50,000, which the UCSD team has decided to share among the people who participate. If they win, you would also receive cash for every person you recruit to the effort! The professor leading the team, Manuel Cebrian, won the challenge two years ago, so his odds of winning again are great"
