I think that it is very interesting to learn how something as (seemingly) simple as computer fonts requires this much low-level thinking to make possible. According to wikipedia, TrueType fonts are made of piecewise quadratic Bezier curves, while OpenType fonts can be made from either quadratic or cubic Bezier curves. This is particularly intriguing to me because I've experimented with both TrueType and OpenType fonts when designing my personal website.
