Just came across this.. and TBH i cant wait to get my hands on one its called the Z Cam and is being developed by "3DV", It is based on Eye toy type technology but it actually measures the depth of movement on screen as demonstrated in this video.. The technology has been in development for 10 years and the product is expected to be released this year at a cost of £100 complete with a game." it will no doubt be a challenge to the Wii controllers..
