We’ve seen The Original Series Tricorder and Type-1 Phaser replicas before, but how about an Original Series Communicator that you can use as a functioning VOIP Internet phone. Pretty sweet, huh? Called the Star Trek Internet Communicator, it’s faithful to the original design and can be used to chat to your shipmates over your favorite 21st century voice-over-IP software including Skype, iChat, MSN Messenger or AIM.
Featuring light-up LED lights and little buttons that play 21 sound clips from the original series, this Star Trek VOIP Communicator even includes that cool sounding chirp (for want of a better word) when you flip open the mesh cover.
The Star Trek Internet Communicator plays nicely with Macs or XP / Vista-based PCs and is available now from Hammacher Schlemmer for $49.95. No subspace frequencies required.
