A movie about the technology which Apple has recently patented. It is not a movie made by Apple but by some researchers.
Fortunately, this is an area where video is much more illustrative than words.
I sometimes get accused of blue sky thinking when I speak of the role of technology in our lives, but while I go on about how access to huge volumes of instantly searchable information is changing us, this video shows a rather near future where we can manipulate it ways that seemed like science fiction just the other day.
Props to Alan Baker for pointing this out to me.
