A free new camera app for iOS called Emojivision allows you to capture images composed entirely of emoji. The app was created by Gabriel O'Flaherty-Chan, according to TechCrunch, which reports that Emojivision uses computational photography to break an image down into its core color palette, then rebuilds it using similarly colored emoji in near-real-time.

The app can be used to take any image, as with the native camera app, and also to apply the emoji filters to existing images located in the phone's camera roll. The app is free, but enthusiastic users can pay $2.79 USD to get additional emoji packs. For developers, the Emojivision project is located with technical details on GitHub.
