LHsee is an educational tool available for Android OS mobile smartphones and tablet PCs. It has been custom designed to provide an accurate and interactive visual representation of complex high-energy physics events recorded by the ATLAS detector. Features include live streaming and reconstruction of collision data from the CERN Large Hadron Collider.
It's interesting that they only released this on the Android platform ONLY and not on iOS, considering that a lot of people that I know of who work at ATLAS use Apple devices.
