From: Allan Wechsler <acwacw@gmail.com> I just had a weird thought. I would like to see two 1000x1000 bit rasters, where the bit (x,y) is marked in the first if Y immediately follows X in any sequence in OEIS, and in the second if Y *eventually* follows X in any sequence.

--Unfortunately I think both ACW's rasters will be entirely black -- or if they are not, then they will be as soon as OEIS adds just one more sequence! I mean, a sequence such that it includes every pair x,y as adjacent elements. (Such as the 2D square spiral...) More interesting 1000x1000 pictures can be imagined. Example, if integer x is followed by integer y in N sequences in OEIS, then color (x,y) with greyscale=MonotoneFunction(N). This picture then will tell us how "related" any two integers x and y are. If you want to be even fancier get all three colors involved, e.g. using RedScale as I just said, BlueScale based on 2-apart-adjacency, GreenScale based on 3-apart.
