Let it be said that I know absolutely nothing about calligraphy, English or otherwise. But I was just screwing around in OneNote (I really need to look through the manual) and stumbled upon the really thick pens.

The possibilities were wholly obvious.

Admittedly, in hindsight, it's not that great (the beginnings of the strokes in particular are hideous, and my 武 doesn't look like a む, =(), but I was pretty proud at the time.

Eastern calligraphy on a graphic tablet is difficult. It should be doable, though. I think the main difficulty stems from the behaviour of the tip of the brush, as the brush moves around in circular motion; even half-circle; the hairs on the tip of the brush can twist and lock giving a kind of stroke that's typical in Japanese calligraphy. So the software can't just have a brush tip shape that varies only in size (based on tablet pressure).

(hmm, looks like people were working on it)

If you can have a look at the free trial of "Corel Painter X". It's got some incredible brushes which are highly configurable. The closest to the one you used would be the "ink pens". Painter also has "calligraphy" brushes but they are usually the non-eastern variety, which is better for european and arabian calligraphy.

If you buy a Wacom graphics tablet, it should come with a complete version of "Corel Painter Essentials" which is a "light" version of the same product, but with which you can produce already incredible stuff.
