The H.O.G.
I was walking around in the tesseract, when I thought of a way to use up the extra wood from making the telescope mirror tester (will post next week). Here is the unfinished version of my H.O.G. Machine (Hands on Graphing). Saves paper! I can split the cubes up in many different ways using wood skewers. I have 3D printer version using biodegradable PLA in a foldable pocket size in the works.
Prime time! Deepest apologies, I had to.
