I learned about serif and san serif typefaces, about varying the amount of space between different letter combinations, about what makes great typography great. It was beautiful, historical, artistically subtle in a way that science can't capture, and I found it fascinating.

Graphic Design, which fulfills aesthetic needs, complies with the laws of form and exigencies of two-dimensional space; which speaks in semiotics, sans-serifs, and geometrics; which abstracts, transforms, translates, rotates, dilates, repeats, mirrors, groups, and regroups, is not good design if it is irrelevant.
