Arimaz's MyDeskFriend is a little penguin that rolls around your desk, has 5 moods, responds to physical input and connects to Facebook. I kinda want one.
It launches in September for just $99, and is meant to be a social media companion. Your friends can interact with it via your Facebook page, and it can read messages off of Facebook to you. Its eyes reflect its mood, and will memorize 10-15 short vocal commands.
