A giant equation is taking form over the course of a few days, on a 46-ft tall "chalkboard" at the corner of Crosby and Broome in NYC. Sponsored by Dow Chemical, it's a mathematical brain teaser with the significance of each term left for the solver to discern. In the first term, for example, the '755' is the length in feet of each side of the great pyramid. Solutions to pieces of the puzzle can be submitted via twitter to @GiantChalkboard. I'm not clear about the commercial aspect of this, or even what exactly "solutionism" is. But if you're a math/puzzle nerd, you'll likely waste lots of time on enjoy it.
