Dieter Krachtus and Chris Deckers are working on Eos, "a project to run Eclipse using Swing widgets exclusively." Having seen NeoOffice, this really shouldn't have surprised me, but it did. I'm not sure if they'll ever get it to really work, but if they do, that would be extremely cool. If nothing else it might make Eclipse look decent. While I prefer Eclipse to Swing-based IDEs like netBeans and IDEA for reasons of functionality, there's little denying that SWT is very old and ugly toolkit. At first glance, Swing apps just look better.
