There is an interesting concept (in my eyes) of fat binaries, and I have an idea of a challenge. Besides the fact that it may not be too feasible in this context, I feel like if anyone can do it, it would be this community. The problem arises from the fact that it may fall into more of a post-programming puzzle.
My idea is a challenge to create the smallest fat binary with the points based on how many systems it works on, divided by how large the size of the file is.
Basically, is the reverse of this question allowed.
