Nintendo is launching a 'Make Your Own Mario Flipnote competition' judged by Shigeru Miyamoto.

To celebrate Mario's 25th anniversary Nintendo are asking you to make your own Mario animation using the DSiWare title Flipnote Studio. The competition will be judged by Shigeru Miyamoto, creator of Mario, Takashi Tezuka, who has worked on Super Mario Bros., Legend of Zelda: Link to the Past and Super Mario Galaxy 2, and Yoshiaki Koizumi, producer of Flipnote Studio.

To participate you must access the 'Flipnote Hatena' menu from within the game. After this you must select one of the two soundtrack options provided and then create your Flipnote using that soundtrack. Entries must be in before December 10th and you can only enter once. For more information check out the official website.

Be sure to check out our Flipnote Studio forum discussion for advice and feedback from other participants.
