Over the last couple months Richard Bair, Martin Brehovsky and I presented talks introducing JavaFX at Devoxx 2008, Sun Paris Tech Day and IJTC 2009 (Irish Java Technologies Conference). There are 2 versions a longer one for Devoxx and a more condensed version for Paris and IJTC. For those of you interested here are the slides and demos:
During the talks we built up a simple demo with what you learn in each section.
Here are the links so you can webstart the demos for the different sections, I started at Demo 2d as that is the first version with working close button which is always helpful
Here is the Netbeans project and source files for these demos so you can play with them.
