A long time ago, there was an iOS app that was quite innovative for the time. The way it worked was that two iDevices on the same Wi-Fi network that wanted to share data (for instance a picture) would launch this app and come to a virtual "table". The edge of the table would be a recipient. To send the picture, the sender would choose what to share and bring it to the table, and then swipe the picture off a particular edge of the screen, and it would slide in on the recipient's device. As far as I can recall, the UI was white.
Can anyone name this app?
