From bottom clockwise: The original picture of J.R. Tolkien (reversed), pallet grid made with Photoshop, the finished mural, and a small thumbnail to show scale. It only took us around 3 hours to complete the mural.
This was a Graphic Arts class group project, we were allowed to only use a pallet of up to 10 different post-it colors, we've used nine colors (the white was the hardest to find!) We decided on a portrait of J.R Tolkien because of the location of the window facing Mt. Pilchuck and the forests beyond the industrial city of Everett, of which nature and technology was a common theme in Tolkien's writings. That, and we all agreed that J.R. Tolkien (and his pipe) is awesome in general XD
