A video of my RubyConf 2008 talk, Simplifying Desktop Development with Glimmer, was posted >>over here<<.
I will revise it before EclipseCon 2009 to reflect the latest advancements in the project.
Note that MonkeyBars, a competing Ruby library that relies on Java Swing, was presented by David Koontz right before my talk, and thus my mention of him at the beginning.
Beware! Typical Eclipse SWT vs Sun Swing rivalry showed up during the talk.
