PS. The fact that any image can be encoded in 32 bytes this way implies that there are only 2^256 possible images — about one hundred and sixteen quattuorvigintillion. That's obviously not literally true, but we are searching for a subsequence of π which is "close enough"; the number of possible images which humans would consider distinct is probably well less than that.

(That is, the vast majority of possible images are "color noise" which all look more or less the same.)
