Puzzle 374: Room and Reason 23

Can you guess what year I made this puzzle in? Here are three hints:
a) The year is very cleverly concealed in the puzzle.
b) It's the same year that motris created this puzzle (which, incidentally, is quite a bit more difficult than this one, and possibly more interesting).
c) I threw this puzzle together 10 minutes ago, inspired by motris's creation above.
