I am a fan of stunt kites. Not the ones that take you up into the air, but the ones that you can fly around on a windy day with your feet on the ground. I would love to get a camera that is small enough to get up there and have a way of making it take some shots.
I came across a ballon with a camera attachment on it that allows you to press a button on the ground and have it take shots from above. It is called the Arial Capture, check it out.

Has anyone seen any actual kites that do this?
You are looking at this the wrong way. You don’t need a smaller camera just a bigger kite 😛
True:)
