As much as we love impromptu dance parties, we're not about to lug around heavy speakers everywhere on the off chance that our friends are suddenly ready to boogie. However, with the Rock-It 3.0 Portable Vibration Speaker ($20), you can turn almost any nearby object - the hollower the better - into a speaker. Grab the nearest box, bowl, or lampshade and listen to the music play. Let's not kid ourselves - the sound quality is not going to be as great as if it were coming through standard speakers, but if you want something compact so you can provide tunes at the beach or while on a hike, this gizmo will certainly do the trick.
