As I just shared over at the TrekPropZone, this is a custom build that came to me by way of YouTube tinkerer "Bink" back in 2010. It's a Bluetooth-enabled speakerphone inside a Star Trek: The Experience communicator shell, and it works fairly well.
April 1 news day at work meant we were allowed to get a little weird with our videos, so I whipped this up for the afternoon. Hope you all enjoy it!
