I wonder if this guy got his Soundwave MP3 Player going in time for the movie. He could have made a killing.
The premise is simple. Someone needs to purchase the rights to use the image of Soundwave, the evil Decepticon Transformer, from Hasbro. Then make a hard disk-based MP3 player out of Soundwave (slightly smaller than the original Transformer toy, though, for portability) that actually transforms. Then sell the individual transforming cassette Transformers (Casseticons, was it?) as individual USB flash-based MP3 players that can be placed inside the larger Soundwave unit to extend its library.
