7 or 8 years ago there was a segment on the local morning news in san diego about some fancy new dvd player. It was to be released in a few months (from the segment being aired back in the day), and the creator was on giving demos about how you could use it to 'play' with movies; replacing swords with light sabers, adding funny hats, rearranging scenes, using a mic to dub dialogue, etc. I haven't seen it since, but this reminded me of it.
