Zapp places the power of high-voltage electricity at your fingertips. Use your iPhone camera's live background and send bolts of lightning to whatever's in view. Simulated lightning bolts follow your touch as your finger crosses the screen. This app is recommended for Super Hero wannabees, fans of atmospheric discharge, amateur bolt throwers and addicts of any other apps that are for amusement only. iTouch users can also use Zapp as it also allows electric charge simulation on photos choosen.
