Have you ever made stupid faces on a webcam before? Chances are you have. And the marketing whizes over at Nike managed to make it even more fun.

Nike Free Face launched in Japan this week, but the app is available anywhere. It will let you contort a 3D version of the super flexible Nike Free Run + sneaker by making weird faces at your webcam.

There's a contest for the best face/shoe combinations with a weekly Nike gift card. Nice. Check out a video below. [Nike Japan via FastCo Create]
