Ballet teaching app is like playing 'Twister'
A smartphone app has been developed which could help teach people to dance.
Created by Game Oven, Bounden requires two people to hold a smartphone, and without letting go, they have to twist and turn their bodies to move a sphere displayed on the screen.
When moved correctly, the phone's users will recreate dance movements choreographed by the Dutch National Ballet.
