New submitter karlnyberg writes with an update to the recently announced de-shredding challenge posted by DARPA: "The team 'All Your Shreds Are Belong To U.S.' has correctly solved all five puzzles, and the Challenge has now ended. You may view the winning team's submissions as well as the complete puzzle solutions by following the links on our homepage. We recognize that many of our participants have devoted countless hours to painstakingly piecing our puzzles back together, and we truly appreciate everyone's efforts. Hopefully you enjoyed the Challenge and learned something new along the way. We certainly did!"
