Some projects are just plain weird. Like this Face Visualizer, one of Daito Manabe's 'body hack' experiments. By sending electric stimuli to a persons face, synchronized to the music, you get a rather funny looking visual representation of what you hear. Perfectly synchronized facial expressions.
There isn't much information on the concept of the project on Manabe's website (or it's in Japanese), and I don't know if there would be a lot to say about it. This seems to be a classic case of "look what I can do!". And it looks funny, so we all want to see it!
