One of my colleagues was biking the other day and in a random parking lot in South Pasadena spotted a van that looked familiar (to him):
Those diagrams ... that van ... he remembered it from a documentary he watched in a physics class:
Seems a team of Feynman's friends and fans banded together to restore the vehicle, which is covered with the famous space/time diagrams Feynman created to understand four-dimensional interactions between particles. It's now a registered "historical vehicle". I wonder if it can go back in time?
