Tyra Banks is the world's premiere renaissance woman. (If you don't believe me, just ask her.) Her resume is so long that she prints it on sky banners and reading it constitutes a full cardio workout.

The Wednesday on the second-to-last episode of America's Next Top Model, Tyra will add another item to her expanding resume: Motion editorial director.

What is a "motion editorial"? Watch the videos below to see Tyra explain the concept to her final four contestants, Kayla, Ann, Jane and Chelsey. The two girls who don't move well enough for their Tyra-nnical director will get the boot for the season finale--which, by the way, airs December 1. Next week is the cycle 15 blooper reel show.





Who will excel at the difficult "looking pretty while moving" task ahead? Check out photos from Wednesday's shoot:
