If you have an iPhone (or video-capable iPod), and you want to learn how to write Japanese kanji characters, have a look at this series of free videos from Emory University that are available in the iTunes store. Just search for “kanji” and you’ll find them.
Side rant: in iTunes why isn’t it possible to 1) select a batch of videos and download them all at once, or 2) select a batch of videos at once to synch to the iPhone? For 100-odd videos it was a pretty tedious procedure. Grrr.
