I'm passionate about typography, and Univers is one of my favorite faces. Besides being clean and unobtrusive, it's just so well thought out. It's a system that works together. The different weights and variations are assigned numbers to distinguish themselves. That always reminded me of the atomic numbers on the periodic table.
I created my own periodic table, comprised of elements of typography. Each 'element' illustrates a particular trait of typography in its abbreviation. I used Univers whenever possible, but switched to more appropriate faces (mainly Garamond) to illustrate features that simply were not available (such as ligatures).
I wanted to keep the poster as clear as possible, so I kept to a two-color scheme of black and pink. The atomic numbers are all different weights and widths of Univers, expressed in those particular weights and widths. I opted to repeat some numbers in the grid rather an include some of the more extreme fonts that might overwhelm/distract from the main features of the elements.
