Tinkering around with my clock projects, I've done an accidental survey of some tools for doing dynamic graphics in web pages.
This is a Java Applet using java.awt.* graphics:http://bolson.org/clock/a2.html
I still think Java is a great language, but it looks like Sun's promise of write-once-run-anywhere GUIs went out with the 1990's.
Also, I'm planning to watch one or more of these roll over this New Year's Eve. ;-)
