What you see below sans pants is an ex Midway employee demonstrating something that looks pretty similar to the Wii's controller using Ready to Rumble
on the Dreamcast. Now, this guy is showing the controller in action many years before the Wii came out and supposedly had the idea for it more than 10 years ago. It's wired version and only does 2 axis but the basic premise is there. Nintendo might be coughing up some bucks to this guy.
