Japanese character screensaver

 Kannasaver is a screensaver that displays random characters from the
 Japanese syllabary, ideally causing them to stick in your memory after

 display basic, extended, and compound characters from hiragana, katakana,
 or both simultaneously.
 You should install a font with Japanese character support before using
