You may not have heard of it but Kite Aerial Photography is quite a widespread hobby. It involves strapping a camera to a kite and flying it over something interesting. The camera can be fired remotely or just on a timer. Serious people build complex radio control rigs to move the camera around and point it in different directions.
Doing silly things with cameras appeals to me so, when I realized that my older compact digital camera (a Nikon Coolpix S1) had a feature to fire a shot every 30 seconds, I just had to give it a go. I built a rig using the Picavet suspension system. Bought a large kite for £30 and took it on holiday to West Wales. The result was terrifying!
