Looks pretty useless. Fun for about 5 minutes.
And I still give them all the thumbs up I can. It's the fun in doing things like this that leads to enjoyment in creating for the computer world. And enjoying what you do is the key to making something amazing. Maybe these folks will not, maybe they will. But they are in the right track.
Have done pretty useless things in my past also, and enjoyed them a lot while doing and while seeing the "finished" product.
I'm still waiting for better innovation in the controller market. I'm hoping for something that combines an arcade stick, numerous buttons, a pen and writing pad... A kiddy version has been out for years for v.smile. They can even integrate it with kinect it makes them feel better since this whole shift away from controllers. I hope controllers dont die all-together. I could never use a kinect (leaning forward/backward is extremely painful) as i am disabled.
