I had already discovered the Generator Blog and the fact that one can easily digitally alter images of road construction signs for personalized messages. So I was interested to see this blog entry about hacking roadsigns in the real world. The intrepid author changed one of his local highway signs to read KLAATU BARADA NIKTO, the phrase that stopped the alien robot in The Day the Earth Stood Still, and another to UFO CROSSING AHEAD.
As more information signage goes digital, this opens up more opportunities for subversion of public messages by the tech-savvy. For example, recently a series of Toronto city train signs were made to read "Harper Eats Babies," a gibe at Canada's new conservative Prime Minister.
