Great apes construct woven tree shelters, using triangulated branches with a coil of leaves inside serving as a lining. Central African Bambuti people construct geodesic woven-branch domes externally covered with a coil of leaves to repel water. Were the first boats made from dome-derived baskets? Were they the arc (teba) of Moses (Hebrew) & Horus (Egyptian, eq. to Torus? see bottom of post), baskets covered with bitumen tar/pitch?
1560s, from L. torus "knot; cushion"
Basking shark vertebrae, from Coastal Paleontology [Unrelated to post title, but cool, like this stonehenge animation]
More info on roof, and how the stones were moved, quite similar to Dick Parry's
idea of how the Giza Pyramid stone blocks were moved in 1/4 circle wood cradles.
rock n roll
"No one knows what this crescent-shaped tool was used for, though it has turned up in association with Clovis points elsewhere. While the tool's middle edges are dull from grinding, its ends remain sharp. It is made of chert from the Green River Formation of southwestern Wyoming and contiguous parts of Utah and Colorado. This is not far from where the cache is believed to have been found, the three corners area where Utah, Wyoming, and Idaho come together."
Crescent-shaped knapped stone (scraper?) from the Holocene have been found at Lake Baikal, Siberia and San Miguel Island California and the the Great Basin of Utah and coastal sites, often of obsidian or chert. Neat pic.

Video on hyper-origami. Math * Computer -> a single flat sheet of paper can form super complex forms. Used for folding metal stents in arteries, and folding mirrors in outer orbit space. http://www.ted.com/index.php/talks/robert_lang_folds_way_new_origami.html
I made a paper sphere by making a takraw ball of 6 paper strips, then another long strip to make 12 trefoil knots (pentagons) which filled in the pentagon holes of the takraw ball. Cool. I'm sure it's possible to make a sphere from one single folded sheet of square paper, but it would be complex hyper-triangulated.
Knots and lashings
Torus: knot or cushion, Latin (Egyptian. Horus?)

Stalactite = stylos, galact = drip... did the first temple columns derive from cave stalactites?
