My Tutor suggested I watch this video by Janet Cardiff and George Bures Miller. (This is only a 6 minute extract.)
I liked this very much, the idea of linking a video with a mobile-phone device and time of past and present in a specific location then filming the handheld mobile phone video within the frame of the present and adding a thought provoking commentary was just brilliant.
This idea could be used in all sorts of ways, I shall add this to my mental toolbox of ideas and themes for future use. This might make a good idea for a story, thriller, love story or horror, plus it would make a good video guide for tourist spots and museums, etc.
