Via: an impressive Doraemon game for kids:

Doreamon has a cool gadget, the Yojigame Pocket (4th dimension pocket), in which he stores just about anything from cars to houses and planes. He also has a helicopter hairband that his friends can use for flying. Epoch has released a video game based on this helicopter hairband! Inspired by the Wii remote controller, the player uses a hairband to control his/her character by moving his/her head in all directions

Why do I blog this? that's an impressive game controller: it allows users to control Doraemon as the character flies through the air using a helicopter strapped unto the head (lean the head forward to go forward, lean the head back to move back, and tilt the head to go sideways)
