The Nintendo DS, first released in 2004, has become one of the bestselling game systems of all time. With the release of the third version of the system, the Nintendo DSi, it might also become the animator-in-training’s best friend.
The DSi features the ability to download games and applications over a wireless network through an “app store” interface. This means that smaller developers can offer the type of software that would not usually make it to store shelves: simple micro-games, unusual game experiences, and applications.
Two applications coming to the DSi offer great potential to transform the little system into a portable animation studio. Moving Notepad and Inchworm are the first of what, hopefully, will become a staple of the DSi store: drawing and animation programs.
Moving Notepad (Flipnote Studios)
From wikipedia: Moving Notepad allows the user to create both word and picture-based notes with the stylus and animate them into a frame-by-frame flipbook-style animation. The user may also add sound to their creations using the DSi's built-in microphone, and either of the DSi's built-in cameras may be used to take pictures for use as frames of animation; such images will be rendered by Moving Notepad into a hand-drawn style.
Moving Notepad has already been released in Japan and is expected to find it’s way to the North American DSi store sometime this year. See my previous post on Moving Memo PAd here.
UPDATE: The North American version of Moving Notepad will be called Flipnote Studios. Nintendo announced at E3 that it will be coming to the DSiware store "this summer".
Inchworm
Inchworm is a drawing and animation application created by an independent developer that just recently announced it will be bringing the software to the DSi in September of this year. This program shows much promise, as it is surprisingly full featured. Inchworm includes the ability to onion skin, add layers, adjust opacity, and adjust animation speed (or timing) for individual frames.
At the inchworm tutorial page, make sure to click on the animation tab to check out the application in action.
