These Were Handmade in the 1800s by Layering Sand. No Glue was Used

Andrew Clemens (1857-1894) was an artist from Dubuque, Iowa but spent most of his life in nearby McGregor. At the age of five Clemens was stricken with encephalitis that left him completely deaf and nearly mute.
At age 13 Clemens began experimenting with sand art, collecting multicolored sands from Iowa’s Pictured Rocks region. He fashioned special tools made from pieces of hickory and fish hooks that he used to arrange the sand in intricate designs. Clemens did not use glue in his artwork, relying on the pressure of the tightly packed surrounding grains to keep his artworks intact. Once an artwork was complete, Clemens would back the jar tightly and seal it.
Clemens had a remarkable ability to break down images and render it grain by grain with each piece of sand akin to a pixel of a digital image. He is thought to have produced hundreds of bottles during his lifetime but few survive today.













Tsunami Ark: Handmade Flood-Proof Floating Wood Capsule



Former Facebook and PayPal employee Chris Robinson is two years into an epic backyard project rising behind his home in Palo Alto: a structure dubbed the Tsunamiball.


A veteran of Silicon Valley with no nautical or construction experience, Robinsin met his wife in Fukushima and, after seeing the disaster unfold, set to work trying to solve the issue of tsunami-proof architecture.


His capsule is 22-foot-long, 10-foot-wide, 8.5-foot-high and built of plywood and epoxy, envisioned in Adobe Illustrator, vetted by engineers then slowly constructed by hand. The inspiration? Seaworthy escape pods and spherical treehouses.


So far he has finished most of the hull but still needs to add buoyant insulation, a structural keel and an electric motor fueled by solar batteries. While his own California home is unlikely to ever go underwater (at least not literally), Robison plans to test the seaworthiness of his creation in the nearby Pacific Ocean, and then perhaps rent the place out on AirBNB. Maybe it can also serve as a prototype for a new kind of disaster-resistant design for coastal areas.
