Pattern Blocks are used in early math and just for fun. Great for drawing mandalas, tilings, and tesselations. Originally written as a toy for my daughter in 1998, this is my most popular app by a landslide. Latest version features full-browser resizing, better email, hundreds of backgrounds, and keystroke shortcuts.
NumBlox Freeplay is a cusinaire rods game. Cusinaire rods (number blocks) are used to teach early math. NumBlox features a simple, clean interface, with rotateable drag and drop blocks on a grid, and a play area that grows to fit your web browser area.
Calligraphy is quite popular. I wrote the original 1997 Java applet as a throwaway programming example - but people kept using it. So I turned it into a real product. Latest version features textured and tinted papers, transparent inks, zoom, print options, Undo support, marker as well as chisel nib, etc.
Calligraphy is now available in Slovene! Translation by Milan Ozimek.

Kuizu is a Japanese vocabulary quiz program I wrote for myself. It features several intermediate level word lists, flash cards, multiple choice quizzing, and matching games. It assumes you want to memorize kanji + kana pronunciation + English meaning. Auto-adjusts word frequency based on success rate, tracks progress and mastery. Can sort wordlist, select which words to use, etc.
Thanks to Laurie Hainke and Yuko Matsuda for contributing 7 word lists!
