This is GNU Unifont, a free Unicode bitmap font by Roman Czyborra. The font contains a glyph for every character in the Basic Multilingual plane. This font is not monospaced, but all letters are built within a 16×16 pixel grid. I am still working on it, but it will eventually have more letters.

This is a font containing every Latin, Greek, and Cyrillic letter I could find.
