From bottom clockwise: The original picture of J.R. Tolkien (reversed), pallet grid, 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
Since this has been up, I've scribbled several quotes from his books and caricatures of his characters all over the notes in the hope that more Tolkien fans would follow suite.
