The cover of the January 2005 issue of Physics Today is supposed to depict what the market square at Tübingen would look like if you were approaching it at 90% the speed of light. Offhand, I’m not sure this is what the square would look like at that speed, but I am sure the colors would be different. All wavelengths would be shorter by more than a factor of two. So, unless that little octagonal pond is actually red, you’ve got a problem with your relativity.
