Donald E. Knuth, Professor Emeritus of The Art of Computer Programming at Stanford University, maintains one of the homelier homepages on the web. But he has a refined eye for design. I’m fascinated by his photographic collection of diamond road signs. Knuth is known for attention to minutia. He invented TeX a system for typesetting and Metafont a format for creating and encoding typefaces on computers. Perhaps it’s his eye for typographical detail that drew his eye to the distinctiveness to be found in common road signs.
