Hi there, I saw your post about using the Kinect and being on top of the couch. There is a new product out now called the Nyko Zoom. It is made to slide over your Kinect and it allows you to stand much closer. I think it is around $20-30 on Amazon. I've heard great things about it.
Also, if you are interested, feel free to come join our Kinect Spark group. We've got lots of stuff going on there...contests, prizes, challenges, reviews, etc. Even a virtual walk across America. If you get a chance, swing on by and check us out.
