This is a (not very good) font designed to emulate the experience of a dot-matrix display; these displays are found on trains, buses, etc. This font supports most characters up to Latin-1 Supplement, and full Unicode support is on the way.

This is a rendition of one of A. V. Hershey's dot fonts from his 1967 paper "Calligraphy for Computers", the "Mathematical" (serif) font. This version is really a hybrid of the original "Mathematical" and "Cartography" fonts, having some symbols such as the circle drawing and map symbols that the "Mathematical" font originally lacked.

This is a clone of Apple 2b Dot-MatrixThis is a thick dot-matrix version of a very popular classic computer (fixing 1 pixel wider than the original), and it's normally used on word processors, electric billboards, etc. Probably a great font!

more arrows, and some fractions!
