Here’s a neat project by artist Nic Wiesinger:
The Van That Thought Out Loud is a roaming billboard for your ideas, expression, thoughts and intentions. It is yours, a vehicle for you the individual to rant or whine, be profound or idiotic, wild or lame. Just email a post to the vehicle along with your name and present location to: [email protected]. Next, wait. The image of your thought spelled on the van will posted for all to see. All interactions involving the van are free.
You can also catch the van at local events, just check out his blog.
