Jim Weaver gave an excellent talk on JavaFX Script last night at the Boulder Java Users Group. He had deep code examples and showcased his NFJS-style winner-wheel example. Always a hit with the audience. His blog has entries about it can be found here and here. I did a little intro talk prior to that on JavaFX Script as well. My slides can be found at slideshare.net along with some of our other past DOSUG presentations as well (just search for DOSUG in the search box).
