Yes I know that this isn't news Dowser, that cover is also on the Wikipedia page I pointed to :) |
<< But have you seen a 3d ambigram like above? >>
I guess Dowser's reply should really have just said: "Yes"
Mine, on the other hand, should really have just said: "No"

The 3D image was generated using the following tool:

Yep, the cover to Douglas Hofstadter's "Godel, Escher, Bach" had a pair of these on the cover. That was, oh... 25 years ago? Hofstadter made the objects himself from a block of wood using a band saw. |
Dammit, I was going to reference the classic work "Copper, Silver, Gold: An Indestructible Metallic Alloy," but it looks like Jim's beaten me to it. |
