I know what you're thinking: "Another 31x45 giant puzzle? But this is puzzle 221! That's nowhere near a nice, round, special number!" Well, I don't give a darn. My muse led me to make a 31x45 giant puzzle, and I followed my muse, and I'm going to post it as puzzle 221. :)
As you can see, good things sometimes come in threes. Things like the numbers 0, 1, 2, and 3. (Sometimes, they also come in THREE's.)
