In a cognitive science class at Northwestern University, the instructors were trying to illustrate the difference between different types of cognition. They asked us to picture a pumpkin. Got it? Good.
Then they asked us to picture the word pumpkin. And to notice the difference. And it took me a few seconds to mentally choose a typeface to use when mentally picturing the word. (I think I settled on Century Gothic.)
All this is by way of saying, you should check out Ben Kiel's talk at STL-Python on Tuesday, February 4th about how Python is used in typeface design. Partly because the brother of Guido van Rossum, Python's creator, is a typeface designer. That's not really the subject of the talk, I just think it's interesting.
