The Bactra Review   Geometry Civilized
As described in a pair of articles by Paulus Gerdes, author of the infamous Marx Demystifies Caclulus (Minneapolis: Marxist Educational Publications, 1985, as vol. 16 in Studies in Marxism). This is one of the silliest books ever written about any mathematical subject, but the techniques Gerdes describes in those articles are simple and practical enough that he's probably not screwed them up.
