It would appear that when MIT isn’t working on top secret Flyfire Swarming Displays, they make Mebots.
What is a Mebot? Think of it as a way of being in the same room with someone, even though that other person is far away. Unfortunately, that other person has to take the form of a crab-like creature.
As you can see, the screen is made so the transmitted person’s head is oversized on this body, but the Mebot can also do an emoticon face as well. By the way, the neck on the Mebot is cable of “three degrees of freedom for simple emotional cues”.
