This is an excerpt page from a book about drawing. The tabled layout of the faces really appeals to the analytical side of me, and the drawing aspect appeals the the creative side of me. Much like a color wheel, this could be considered an emotion wheel. I think it's funny how they couldn't come up with a word for EVERY combination. For instance, there was no word to describe DISGUST + SURPRISE, so they simply called it "YOU ATE IT??". And ANGER + SURPRISE simply == "WTF?".
