Talk about bringing people together. The free Mosaic app allows users to sync multiple iPhones or iPads to create one giant screen on which to share files or view photos and video--all with just a swipe to connect the devices.

It started with three college students who wanted a simple way to physically connect their mobile devices. One had been working on a file-transfer interface called Swÿp, and the three decided to combine its technology with what's known as "screen-stitching." The founders, all of whom have been programming and developing for Apple's iOS from an early age, created Mosaic during PennApps, the world's largest college hackathon, and launched it in April.

"We tried to make an interface that was as intuitive as you would expect something like that to be," says co-founder Zain Shah. "Right now mobile phones tend to separate people, isolating them physically. But with something like this, you can collaborate with your devices and enjoy [them] together."
