People would film the birds at night with their iphones and cypher the messages or bitcoin addresses, and if they liked the idea because they love animals and reckon they would feel we were giving them more importance, or for any other reason, like they just like it and have fun trying to find out and donating to the bitcoin addresses that was providing it.
The devices could use the kinetic energy to feed the eletricity for the lights to pulse (dynamos, like bikes use) and it would have just a small battery for the microcontroller of it.
You could love the bird sending tiny satoshis whenever you would see it again.
OMG, I had no idea Twist was into bitcoin. So how are Shout, Kiki & Marina feeling about this idea? Are they on board as well?
