Von Wired: Bacon Fat Keyboard Lets Real Birds Tweet.
Birds on Twitter is the brainchild of Voldemars Dudum, a writer at Latvian weekly magazine Ir. He has set up a keyboard with pieces of unsalted bacon fat screwed onto each of the keys. The keyboard is placed in front of a webcam in the village of Sarnate on the west coast of Latvia, where temperatures can plummet to minus 4.
The birds are attracted to the bacon fat — which provides them with plenty of energy in the cold weather — and land on the keyboard to peck at the keys. The screws serve to add weight to each of the keys to ensure that the light birds can provide enough pressure to depress them.
