NPL Convention 2013
The 2013 NPL Extravaganza in Austin, Texas was named A Matter Of Con Science. It was constructed and run by Mark Halpin, Darren Rigby, and Dave Shukan. The theme was a scientific megacorporation -- NPLabs -- with fingers in various different fields, represented by the names of the puzzles. Recently they uncovered pieces of the world's first thinking machine and were unable to reconstruct it, but hoped that the crowd will be able to prove themselves worthy of gaining access to the artifacts (by completing puzzles in various fields), and upon being granted access can reassemble the thinking machine correctly.
