One light short of an intersection

Okay, that title is humorous, but I would have great respect for the guy in this story if he had built this himself or been more careful in its use. Instead he bought if off of eBay and used it so much that traffic engineers got suspicious and were able to identify him. Perhaps the designer of this device is a bit more judicious and is still out there?

Seriously, I'm not condoning this illegal behavior, but my inner-tinkerer has to applaud the ingenuity reflected in someone designing and building this device to take advantage of the system. I do wonder how many more are out there, and whether that extremely short green light this morning was caused by someone going the other direction with one of these puppies in his or her car...
