Balloons! is the great new app which allows you to launch virtual helium balloons and track their progress around the world.
Choose a balloon, attach your photo and message to it, then launch it into the sky. It then drifts around the world to be caught by other users. They add their own photo and message and send it on its way again.
A Balloon tracker lets you see the progress of your balloons and read the tags added by people who have caught them.
By labelling balloons with twitter ids, users can get in touch with each other after their chance balloon encounter!
Balloons! – the fun, environmentally friendly alternative to a real helium balloon launch.
