A CGP Grey video about why pentagons are bad at tiling and why hexagons are so special, in his usual playful style. It touches on honeycombs and tiling in nature.

Recommended in hexagon-grid threads as a fun but informative overview, and sometimes dropped as a light joke.

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]

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.

Good idea! Honeycombs are hexagons, and they tile the plane. And they're made of triangles. [VIDEO] We need parks, not car parks! Rather getting zapped on power lines or pooping on cars, the birds can have branches to sit in and flower beds to fertilise.

"Hexagons are the bestagons" according to CGP Grey. [VIDEO] Personally I prefer fractals. A 6-sided hexagon is just 2* 3-sided triangles. Or 6 of them, depending how you prefer to tile the plane. [LINK] So how about a day schedule organised by Sierpinski triangles? Lots of space in the middle for resting.

But I thought Hexagons were the Bestagons! ;) [VIDEO] Hexagons, Pentagons, and Geodesic Domes [LINK] Introduction to Hexagonal Geodesic Domes [LINK]
