A neighbor I had before I moved who was Japanese had this cool colored paper that was the same idea. You use water on it to practice, then it fades away. Except it was more fun than a blackboard because it was in all these fun colors! She brought it over from Japan, so I doubt you could find it in the US... I didn't see it in Japan either, though^_^; Then again, I wasn't really looking.
