A fascinating [blog post][post] by Norbert Landsteiner about how the old DEC
terminals (VT100, etc) rendered text. The glyphs in the terminal's ROM are
pretty dramatically different from how they're actually rendered due to a
vertical pixel doubling algorithm, and the physical effects of shooting
phosphors with electron beams.
