Have you read PopCo by Scarlett Thomas? I just finished it about a week ago, which is the only reason I understand anything in your first numbered link. :) The main character's grandpa seems to be based on Leo Marks, but without the poem-codes.

I like the idea of llama font, but since seeing "Llamas with Hats" I'm worried the llama-font llamas will all turn to look at me with hand-eating hunger in their eyes. (that must be my record for most "llamas" used in a sentence)
