Elementary: The Periodic Table Of Typefaces
Somebody went and made a periodic table of typefaces featuring "100 of the most popular, influential and notorious typefaces today". This is it. Click HERE to see a high-res version, then go ahead and print it out and post it up on your cubicle wall. That way when somebody pokes their head in to ask you about doing some work you can yell, "TALK TO THE PERIODIC TABLE....OF TYPEFACES!". Then they'll all think you're crazy and leave you to your Solitaire.
