Hexagons are, after all, the bestagons. On the very very low chance you haven't seen this: [VIDEO] And if you don't know who CGP Grey is and are wondering how this comment fits into HN, I can only offer that he's cashing in on his reputation a bit with the fun tone, but IMO the video is also interesting informationally.

CGP Grey did a video about hexagons recently. I mean, there's only so much you can say about hexagons really, but he manages to cover a lot of ground. [VIDEO]
