ArcadiaVincennes, maker of maps such as DM-UCMP-PleasantValley and DM-UCMP-Xanadu (both for UT2004) has released a few Kismet tutorials on his site. Among the topics you'll find there are how to create breakable glass, or raising and lowering liquids. Many of them are even available in either french or german - sometimes both. Definitely worth a look for any aspiring UT3 level designer!
