Guess what I managed to create in G’MIC without the use of BIGINT library?
Still, some bugs though. I’m not sure how to properly convert a image representing a large number into a image of binary yet it seems. Ooh, so close. I wish dec2bin and bin2dec would allow for humongous digits for this case or something like that.

EDIT: I fixed the bug. 
It looks like this fun filter is happening though I can’t imagine a real use case of this other than teaching students how loading and exporting file work.
