The way things are going, someone might eventually try to cram a supercomputer into a Nintendo DS. Just as we were discussing a project to develop a synthesizer for the handheld, a new product comes along to teach Japanese calligraphy on it.
Bimoji Training (translation: Beautiful Letter Training) is being touted as a game, but we know better: It'll probably be co-opted by educators because it emphasizes teacher feedback. We just hope that the touch screen's sensitivity is up to par, lest it be an exercise in frustration (remember Palm's Graffiti?)
No matter how it works, though, we totally agree with Techabob on one point: The best thing about it is the stylus, which resembles a kanji brush.
