The swarm stuff is neat, but has been done in RTS games. Nothing really revolutionary, except that it's never been done for swarms, using a touch table. The work defines some easy gestures and methods that have been studied and found to be what the majority of people would naturally do.
What I find truly revolutionary about this interface is the dream controller. It doesn't get much play in the video, but it is remarkable. You put your hand down, and it draws the controller around it. It's exact every time. No matter what size hand, or orientation, it draws it perfectly for 100% of the human population. No more xbox/ps3 controllers that by their physical nature can only be built to be comfortable for the average. (50% of the population.) Having the tactile feedback of a keyboard or gamepad button has it's benefits, but if the controller is drawn directly under your hand, You can very quickly learn to press a button without having to feel it.
Having this possibility opens up a whole new world of controller design with applications in video games, touch screens apps, every day appliances, and more. We can rethink controller design, and make the controller conform to the user, rather than the user conforming to the controller. I think it has a lot of potential, and am looking forward to seeing where this goes.
