Combinatorics isn't, but... coloring grids of squares?

Not that I really have anything against abstract mathematics. It's still very cool, but it's just not going to get me very excited - or at least this exact branch of it, I guess.

I'm not one to say that coloring grids of squares sounds fascinating to me, but nandemo's point still holds -- as far as mathematics goes, it's pretty concrete.
