We didn't get any more details about Microsoft's Project Natal add-on for Xbox 360 from the X10 event, but tonight Smallville viewers got to watch someone else whipping their arms and legs around trying to catch imaginary balls flying out of their TV screen. Short of some actual time gesticulating wildly in front of that motion sensing cam this is the closest thing we've got to actually using it, but as the clip (embedded after the break) shows, girls are likely to be more impressed by someone that can fly.
