FloatO

Dan Monaghan developed an iOS prototype that presents individual frames from the position they were taken using AR

App takes photos, then leaves them floating where they were taken. It's the beginning of much more, the demo is just the beginning of an iOS App that will have sharing, lots of different "modes". Currently, it's just a tool for taking very weird photos. It's smooth, running 60fps with 150 photo frustums sitting there easily.
My first real "app" - and it actually does something, it's a great feeling watching someone use it, some people are really engrossed in the visual experience, there is usually no stuttering or latency, which for camera tracking even in night conditions is great with the contrasty colors..
