A U.S.S. Enterprise Bluetooth speaker by the folks at Thinkgeek:

The Star Trek TNG U.S.S. Enterprise NCC-1701-D Bluetooth Speaker is full of the details you demand. And, of course, it features lights and sound effects. It connects to your phone or a Bluetooth-compatible device of your choice, allowing you to route calls to the captain’s ready room, if you so desire. Or play tunes appropriate to your holodeck. And, like our faux April Fool’s product from a few years ago, you can even fall asleep listening to the thrum of the Enterprise-D’s engines. We’d write more about how awesome it is, but we’re getting a bit sleepy testing it out.
