You want awesome audio, don't buy this. Depending on what you connect the Rock-It to, the sound will come out pale and a little rickety—but you can't deny how effing cool it is. The sheer engineering awesomeness is enough to secure it a place on this list. Just connect the vibrating speaker onto any box or container, plug it into your iPod or computer, and listen. That's it. Anything automatically becomes a speaker. Beats the hell out of any science fair project you ever made.
