I have been geeking out recently on Blaise Agüera y Arcas talks about his BFF interpreter most recently at the Santa Fe Institute and how it can produce information stability out of noise using simple primitives in Brainfuck. I am looking forward to his two books on the subject and recommend checking his talks if you are in the small category of people interested in BF interpreters.
