OrigAudio Rock-It 2.0 Speaker

While this type of speaker system isn't exactly new, it is one of the cleaner designs I have seen.  The OrigAudio Rock-It 2.0 Portable Speaker turns almost anything into a speaker.  Don't expect ear shattering sound out of this little speaker, but it sure is handy in a pinch.  Yours for just over $40 here.
