I think we can create a sign board like this
A BIG Belly SNAIL walknig from a sign board that says "11/16/01" (Processing Date) to another sign board that says "12/16/01" (Processing Date) and the distance says 30 days, travel time says 400 days.
Any more ideas to make it more intuitive and funny are welcome.
