Party wants you to reach the moon, all in the name of a manga. The N.Y./Tokyo-based agency recently launched this Moon Jump app that every week invites its users to simultaneously jump as high as they can--the goal being to collectively leap the distance between the earth and the moon. A countdown clock keeps you on your toes for each week's jump. The app is a fun promotion for Kodansha's Space Brothers manga, about two siblings aspiring to be astronauts. Check out the Moon Jump site for more info (in Japanese only).
