Using barbed wire fences to create a telephone network makes so much sense, but it was new to me until I stumbled upon this fascinating article. Always enjoy reading about rural ingenuity. Favourite fact: the barbed wire networks sometimes used corn cobs, cow horns, or glass bottles as insulators!

Lori Emerson’s website seems full of interesting projects, and I especially love the table of contents from her upcoming book Other Networks: A Radical Technology Sourcebook.
