Although it is unable to use "subspace" frequencies for instantaneous interstellar communication, this is the Star Trek communicator that serves as an internet phone. Faithful to the original design first seen in the original series, it plugs into a Mac or a PC running Windows XP, Vista, or Windows 7 using its built-in USB cable, allowing you to use it to make internet phone calls (requires broadband internet connection and your preferred voice-over-IP software). Widely claimed to have served as the inspiration for the modern cell phone, the communicator "chirps" when flipped open, one of the 21 included sound clips from the original series. The hallmark Moiré-patterned circle lights up using LEDs. 4 1/4" L x 2 3/4" W x 1" D. (5 oz.)
