Picture Sundays: Compulsory Chickens

I found this old ad posted in Facebook.

Even the smallest back yard has room for a flock large enough to supply the house with eggs. The cost of maintaining such a flock is small. Table and kitchen waste provide much of the feed for the hens. They require little attention–only a few minutes a day.

An Interested child, old enough to take a little responsibility, can care for a few fowls as well as a grown person.

Every back yard in the United Sates should contribute its share to a bumper crop of poultry and eggs in 1918.

In time of Peace a Profitable Recreation
In time of War a Patriotic Duty

Picture Sundays: Hyperbolic Crochet

Spotted at the Institute for Figuring in Los Angeles, a piece from their Hyperbolic Crochet Coral Reef. About the process:

The inspiration for making crochet reef forms begins with the technique of “hyperbolic crochet” discovered in 1997 by Cornell University mathematician Dr. Daina Taimina. The Wertheim sisters adopted Dr Taimina’s techniques and elaborated upon them to develop a whole taxonomy of reef-life forms. Loopy “kelps”, fringed “anemones”, crenelated “sea slugs”, and curlicued “corals” have all been modeled with these methods. The basic process for making these forms is a simple pattern or algorithm, which on its own produces a mathematically pure shape, but by varying or mutating this algorithm, endless variations and permutations of shape and form can be produced.

And, yes, they have a how-to book if you’d like to try this on your own.
