Optical illusion

I don't think any of you are aware of this, but the tiling on the right appears to be an optical illusion that the hexagons are not regular in that they alternate between 2 lengths: short-long-short-long-short-long. Georgia guy 22:36, 29 August 2006 (UTC)

I noticed it too when I last edited this page. It seems to be amplified by the bright colors and small thumbnail size. When I looked at it with a width of 1000px, the effect was less noticeable, although still perceptible. Hyenaste (tell) 22:49, 29 August 2006 (UTC)

Outlines of letters -- needs clarification.

The first paragraph contains the statement: "When spelled uppercase, the outlines of the letters E and H (and I in a slab serif font) are all dodecagons."

It took me a while to figure out what this statement was saying, and the article should either have an illustration to go along with this statement, or better examples should be used. --Heath 21:26, 9 January 2007 (UTC)

Agreed. I don't see that the letters suggest anything more than a hexagon to contain them. Wdfarmer 22:05, 29 July 2007 (UTC)

Well, Miss Elk, this theory of yours seems to have hit the nail on the head. —Tamfang (talk) 02:52, 21 August 2014 (UTC)


I'm not a geometer, but this article should probably link to Cross or "plus-sign" at some point since that's undoubtedly the most common dodecagon in use — atchius (msg) 14:26, 1 August 2015 (UTC)
