OK, there are plenty of similar "dot" fonts out there (either free or not) so, there is not much of an innovation here ... But what about those variations! 30 monospaced "dot" fonts in 6 alternates (round, square, diamond, plus, minus, vertical) and 2 styles (normal and unicase), together with 3 non-monospaced condensed variations (round, square, diamond). Most of the 30 monospaced fonts can be used interchangeably, since they share the same width, allowing you to create stunning layering effects.

If you want though to use them in a screen project, try using either BPdots or BPdotsSquares (normal or unicase) in 10px font-size or, alternatively, BPdotsCondensed in 26px font-size. They look great! Unfortunately, I can't say the same for the rest of the fonts or for other pixel sizes ...
