I looked at one title on a computer; it was an interactive guide on how to draw anime characters, and was published by IBM. The program was of the usual multimedia slideshow variety, with each page having some text/graphics and Back/Forward buttons, as well as a simple drawing area, where you followed instructions. These included drawing the head, then two circles for the eyes, and a few more things, and then choosing colours for the face and such. I didn't buy the program, though, as it was Windows-only and required Microsoft Word for part of it, for some reason.
