DS Daily: Moved by Moving Memo Pad?

Of all the games and minigames released as part of Nintendo's early DSiWare lineup in Japan, the star is an unlikely little program called Ugoku Memo-chou, or Moving Memo Pad. The cute drawing program allows users to create animations and add sound -- and, most importantly, to put those animations on the Internet to share with their friends and the community at large.

Does the idea of (basically) a hand-drawn YouTube appeal to you? We've sort of gauged your relative interest in the DSi hardware previously, but what do you think about this program? Useless fluff or a genuine killer app? Or just fun?
