SMS Sent to the Sky
"Amodal Suspension" is an interactive installation where people could send short text messages to each other using a cell phone or web browser. So far, that's quite normal. The twist however, lays in the fact that rather than being sent directly, the messages are encoded as unique sequences of flashes and sent to the sky!
The signaling works in a way that is similar to Morse code(intensity of lights represent different text characters.) Each message, once encoded, is “suspended” in the sky of Yamaguchi. An email is sent to the intended recipient to notify him or her that “a message was waiting for them in the sky of Yamaguchi”.

This maybe old news as "Amodal Suspension" opened on November 1st, 2003 with messages sent by astronauts Pedro Duque and Mamoru Mohri, but it's still worth a post.
