Dutch Guy Hacks Traffic Sign (vid)

This is part of a Dutch viral campaign for some IT school/company. They have put a bunch out now with the same guy.

A quick translation (with Babel Fish) off some dutch site regarding this video: "viral campaign for itafstuderen.nl but if you ask it me is this nevertheless of the best viral campaign which is ever made."

Someone did this outside my dorm at MIT: http://aaroniba.net/misc/nerdxing.jpg

Wow, that's pretty sweet - i wonder if he was caught. Can anybody translate/explain the vid?
