Shows the angles in degrees and radians. Does not have sines and cosines (the coordinates). Features raised quadrant lines for ease of use.

NEW: I'm thinking of offering this for sale on Shapeways! Tell me what you think!

New news: I fixed. I'm so so sorry for anyone who may have tried to reference this.
