Art Live app for iPhone and iPad

The Augmented Reality Platform For Art
This new technology allows artists to create new dimensions of art by linking classical with digital art. The digital layer opens the doors to a whole new world of possibilities. Artists can take visitors on a journey in time and explain what lies behind, enhance the artwork or tell a story. This new world can be unlocked by any smartphone or tablet and offer an extended and emotional experience.
