For MTV, this was for the Viewer’s Choice Award for the MTV Video Music Awards. It essentially involved firing the “Moonman” statues out of a cannon in 3D, at the group, singer, rapper, etc., that you wanted to vote for. This game was used to gather all the votes for the 2005 VMAs in Miami, hosted by Sean “Diddy” Combs.
The ultimate winner, after all the “votes” were tallied, was Green Day, for their song American Idiot.
