A lot depends on typography and convention as well. For example, Maxwell's equations in raw form are HUGE. It's only after you compress them by inventing short hand for div and grade, they can be fit on T-Shirt. Even then integral forms does not feel as elegant. Similarly the field equations for General Relativity in "raw" form huge and ugly (involving 4X4 matrix). It's only after you shorten them using tensor notation they start feeling elegant. I'm not sure we have analog for this in art world. However the technique in this article is interesting because you can extend it to other domains. How about finding out which algorithms are "beautiful"? I think the most beautiful algorithm ever invented is binary search.
