Exactly 8,024 in this case! 31-year-old designer Ben Brucker, of an eBay Enterprise-owned commerce design agency called The Shop in San Francisco, decided the walls of his office were a bit too lackluster. He set out to design some mock-ups of the super hero theme he decided on and calculated how many of each color of Post-it notes that he would need. Each piece is 34 Post-its high. And it took over 12 hours and 12 colleagues to finish the job. The results are fantastic!
