Programmable traffic signs have been around for a while, and although the locals in some areas (*cough* Cambridge, Mass *cough*) have gotten used to it, widespread instructions on programmable sign hacking have caused a veritable epidemic.

If we want to find the earliest incarnation of road sign hacking, we need look no further than MIT. While the rest of us might see giant sign hacking as a relatively new pastime, at MIT it’s considered an old favorite. The above sign was done as part of a recent string of MIT pranks. Clever, but I personally prefer those that warn of an impending zombie apocalypse or raptor attack.
