An interesting direction. A couple years ago, I wrote up some ideas about a "jittery" drawing function that could take preset shape data and draw it with a bit of random x & y offset on each point, for variant renderings.

So on the train yesterday morning I hand-wrote an editor and player in pseudocode, then last night got it working fairly quickly, along with a simple set of glyphs and most of a blocky alphabet. These are some screen captures of the result.
