LightBomber
Create light paintings in the dark with this photography app.
Grab anything that lights up, head into a dark place, and then start flailing around and allow LightBomber to capture the moment. Light paintings can be uploaded for the entire LightBomber community to see, or you can share your creations via Facebook, Twitter, email, or MMS. The app also includes a vast selection of lights and colors to paint with.
