Here's a currently hot demonstration video for software that basically works like a very powerful vocoder, only with video clips; you can cross modulate one bit of complex media with another. The video makes clear what the thing does if you're not familiar with vocoders, much more interesting is the question raised by the process of where "intellectual property" fits in if something isn't so much sampled as it becomes a carrier wave or pattern.
