Google, UC Berkeley, NASA, and others are teaming up to encourage people who view the August solar eclipse to share their videos and photos with the aim of making a two hour long movie showing changes in the Sun's corona in real time, among other things. They will be releasing an app and selling cheap tripods for phones so that people's phones can collect data "hands off" while they watch the eclipse.
