Expository article on simplicial sets

Greg Friedman has written one of the greatest expository articles of advanced mathematics that I’ve ever read: An elementary illustrated introduction to simplicial sets. The combinatorial notion of simplicial set completely captures the homotopy of simple spaces (such as CW complexes). I never made any headway in understanding this until I read Friedman’s article.
