Finally! My first augmented reality app Cactus.AR is on appstore!!)
[link]

All 3d models\textures\animation and animation logic programming are done by me.
Used Unity3d and String.AR library to build the app.
Right now i'm havely returned to programming and scientific work. And i really like that, because i can really do something that is much more beyong a single beatiful picture.
So i'm doing a deep researches in CoputerVision branch and OpenCV library. And my goal is markerless augmented reality. I have developed a totally new way of augmenting reality without any hardcoded markers and i already achieved good first results.
