I have seen some photos of wildly decorated cars before, but didn’t know it was more than a few odd people going out and doing it… apparently, it is a regular event celebrated with parades and even a art car circuit of events!

Note: Lots of pics, might be slow to load. The video at the bottom of the pics has some really interesting vehicles in it! Please note: The gadling blog site with all the pics has a million links on it… I did not follow most of them, so surf at your own risk peeps.
