The contract I received was full of red flags. It required that I not work in 3D imaging for 12 months after my termination (that could be argued to be all computing) and no augmented reality for 24 months after termination. As AR seems to be all the rage and perhaps the "next big thing" I didn't want to gain experience to then never be able to use it. I would have been happy to sign away these things if it was stated to be only related to the actual company.
