Wally Wallington demonstrated how a single person can manipulate massive monoliths, or how they could have been moved in ancient times.
He claims that a pyramid could be completed using primitive tools in 25-year with only 520 workers.
Another example of us not inventing 3D printing! :)
Butterflies & moths aren't the only insects that spin cocoons. Some chrysomelidae leaf beetles (instead of a silky & fabric-like substance) use a process with a foamy secretion which vaguely resemble a 3D printing process

Could watch these all day. Amazing how this simple construction can have endless possibilities.
A Moore curve is a continuous fractal space-filling curve which is a variant of the Hilbert curve. Precisely, it is the loop version of the Hilbert curve and it can also be drawn with epicycles bit.ly/2v8L9qI | bit.ly/2w9QxOI [source: bit.ly/2otNPOZ]

Fantastic article by Siemens Robin Bornoff discussing empirical and computational analysis of fluid dynamics, mechanical and optical properties of fluids and rheoscopic fluids. There's a great simulation of a Vortex Dome!
