the flying speakers by amit zoran from usa
designer's own words:
The FLYING SPEAKERS is a big load speaker construction, assembled on a huge helium balloon. The balloon can fly and navigate in order to optimize its location according to changes in environmental acoustic conditions (like wind direction or location of the audience). The FLYING SPEAKERS is a great solution to variety of applications, like open field rock concert or monitoring bathers in the sea.
