Here is my latest toy. I made myself a Kanji studying tool. It took me only few hours to build using QtRuby. I find it pretty amazing what I built in this short amount of time even though I don't have much experience with this technology. It is a really impressive technology.
I build up a small kexi (sqlite3) database, which I open with ActiveRecord. I could have used Qt's SQL module, but I'm so used to AR that I did not bother.
I named it kikkanji because I first intended to create a kicker panel applet. but, panel applets are not yet possible with QtRuby. so I had to wait. I instead used Qt Designer and created myself a main window.

comments and feature request are definitely welcome.
