Blah Box is the result of the accumulation of ideas Eric had while trying to design a simple mechanism for the box containing the DDD Burr Puzzle. He wanted to make a simple trick opening mechanism for DDD, but in the end, discarded the idea because it would overly increase the price of the puzzle. He did come out of the design session with some solid ideas, which, when combined, turned into a rather interesting box on their own. Eric was feeling rather "Blah" about his failure with DDD and decided to name this new box after that feeling.
