This is what 1px-wide font looks like
Cool post from boing boing on Matt Sarnoff’s awesome Subpixel Text Encoding work.
Millitext is a “font” whose glyphs are just one pixel wide. But it’s really a clever exploitation of how subpixels — the individual red, green and blue lights of an LCD display — are triggered by pixels of certain colors. For example, a magenta pixel triggers the red and blue subpixels, leaving the green one dark between them.
