I have no idea if this is a concept or some geek’s elaborate prank in order to get girls or something. It could be a modified cassette player, but somehow I doubt it. You would need a few AA batteries at least. All I know is that had the actual iPod and Walkman merged in the 80’s, this would be the result. I suppose it would download music off of itunes, and store it on it’s cassette hard drive. When that casette is full, insert another and begin again. Very bizarre, but a cool pic.
