QMx Interactive has created the Farnsworth Video Communicator, which let's you turn your iPhone (or iPad and iPod Touch) into a Farnsworth. I've already sent and received my first messages and I LOVE it. Plus the messages from Claudia and Artie are adorable ;-)
Check out the Farnsworth Video Communicator in the App Store.
p.s. My boss and I have a little bet on how many WH13 geeks I can get to DL it, so if ya love me and wanna help me win... ::grin::
