In the summer of 1995 I was reading Doug Hofstadter's Fluid Concepts and Creative Analogies and fell in love a bit with the reduced typographic domain of "grid fonts" he studied in there. I wrote a little C++ to let me edit them on the computer. Even though the source code to the editor has apparently, ambifortunately, been lost, I did manage to find a bunch of the fonts I'd made back then. Below they are rendered from the original data. (probably the majority are my own work, but it wouldn't surprise me if I'd transcribed some fonts from Hofstadter's book - if you happen to notice such a coincidence, I'd appreciate knowing)
