Unique Presentation Fonts

This kind of font would consist of a program or script to be used in generating each letter. Rather than every "A" looking the same, the letter would be slightly different in each iteration, with each iteration's letters designed to look good together. For example, a program could describe a slightly curvy "A" with more of a curve on top, and with a background that looks like oil paint.

The font interpreter would then generate a new iteration of that with each letter typed. Programs making use of the font would return the unique ID of letters immediately around the letter typed to the interpreter. The interpreter would then generate a letter that would have oil-paint-like strokes that line up together.

Each letter would be largely the same and easily recognizable as the letter, but have more or less of a curve in different parts, with very slightly different line widths, and a different color or image gradient in the background if so desired.

The advanced version allows arbitrary degrees and types of inputs such that the interpreter run on a compatible machine could make brighter colors if the room is bright, automatically contrast against a non-font background, or even animate based on the user's probable mood.
