Interesting videos relating to hexagons

The following is a selection of interesting hexagon-related videos embedded from around the internet—mostly from Youtube. I don't really quite know how to classify this page, since it does not fit into my established organizational structure for this site, but I wanted a central page for the non-date-sorted collection of important hexagon-related videos outside of the Hexblog. For local videos made by Hexnet.org, please also see our short video collection in the Library. Thank you.

Face Centered Cubic Structure

This short video demonstrates both the hexagonal "layer" structure as well as the cubic unit cell structure of the face-centered cubic system:

Bubble Packing Dynamics

In this video we see demonstrated one of the fundamental principles underlying the ubiquity of hexagons in the natural world: Individual bubbles, in attempting to approximate spherical enclosures of their volumes while being pushed up against neighboring bubbles, naturally tend towards a hexagonally-packed configuration. The same general behavior is seen in such diverse phenomena as hexagonal convection cells, hexagonal arrangements in plant and animal structures, and so on. See also: Weaire-Phelan structure.

Flower of life standing wave (cymatics)

This is one of a series of cymatic wave videos by kelemengabi.

Origami Basics: Hexagon

This video provides a pertinent and informative introduction to constructing hexagonal geometries from square precursors:

Seasame Street: Geometry of Circles

I have linked to the following video from elsewhere on this site, but it bears repeating here:

Sacred Geometry: Metatron's Cube

This video is part of a series on sacred geometry by CGimaging.

Project Lucifer, The Silver Surfer, and The Second Sun

This is sort of out of left field, but I think it makes a lot of pertinent poetic/aesthetic points about the ontological and social significance of hexagons. The "second sun" thing is not actually possible under the extant laws of physics though, so don't worry about it:

The Hexagon - Nature's Perfect Shape

These people seem to be selling some sort of hexagonal modular building scheme. I haven't looked into it too closely, but the title alone is obviously amazing.

Vitalizer Plus (hexagonal water!)

This is just completely preposterous:

I don't actually spend that much time perusing online videos, so if you know of an embeddable hexagon-related video that might make a relevant addition to this page, please contact me. Thank you.
