Millitext is a font whose glyphs are just one pixel wide. It depends on a clever exploitation of how subpixels -- the individual red, green and blue lights of an LCD display -- are triggered by certain colors. For example, magenta triggers the red and blue subpixels, leaving the green one dark between them.
The result is above. But here's what the bitmap image would look like scaled up, on the wrong sort of screen, or simple as seen from a distance where you can't tell apart individual subpixels.
