Rymdresan is an interactive guide to the Space Trip exhibition by ESA Astronaut Christer Fuglesang at Visualiseringscenter C in Norrköping, Sweden. The app automatically detects and tracks photos in the exhibition using Augmented Reality technology, and overlays "hotspots" containing additional text and audio information directly on top of each photo. Just point the camera towards a photo on the wall, and have fun exploring!
