What is it?
Parametric fonts are fonts that spring to life when a few parameters are set. Some systems work by interpolating (similar to morphing) from two or more master designs for each character. Other systems extrapolate from a central master. The most advanced and complex systems generate whole fonts from a single, very cleverly designed, master font.
