Time to tell your Wii-playing munchkins at home to step aside. Daddy’s got a brand new toy.

This software for the Nintendo Wii is the first product to analyze the full swing in 3D and give personal feedback. Players stand on a Wii Balance Board, grip the gyroscopic MotionPlus controller as they would a club and make a swing. The computer traces the path compared to the ideal swing, while also analyzing weight shift, tempo, clubface rotation and other aspects. Using video from his “7 Steps to a Better Golf Swing,” David Leadbetter appears on screen to offer instruction and drills. You can also play a practice round, with video Lead offering tips after each shot.

The feedback and tips are terrific, but Nintendo could really improve the system if it came out with a Wii golf club. The square-shaped controller isn’t round like a real grip so it’s a little awkward trying to swing it like a real club.
