The Black Diamond III from Acase is a speaker that marries Bluetooth, music, and light into one aesthetically pleasing speaker.

Acase is making sure diamonds are just a girl's best friend anymore.  It works with any Bluetooth-enabled device or can be connected with a USB.  The lights change depending on the music and will pulse to different beats.  And packed into this little glowing orb are the speakers, a subwoofer, the Bluetooth receiver, lights, and a storage for the remote. Plus, it looks great on a bookshelf or desk.  If anything, it's a cool conversation-starter.

The remote controls the volume and lighting; you can change the color and brightness to match the mood you want to create.

You can grab it at Amazon for $120 and free shipping.
