I've now removed the Odeo option as they are having loads of issues and are very broken at the moment. I have also put up the first experiment with the audio files.
I wanted to use some maps but the ones I had were copyright so I am learning all about the world of map copyrights now. In the meantime I am also looking into opensource options. The Dislocate Exhibition opens today in Japan! I will be evolving the video and audio for 'Show me the way' throughout the exhibition and working with Kevan to make a whole series... should be fun :)
