looking for complex code example for best swing / MVC practices

Hello,

I've been using Swing to develop complex GUI (standalone applications)
for quite some time and feel confident with the language, the
components, the layout, all the graphic part basically, however I get
the feeling I still can't grasp the good way of dealing with MVC /
separating business logic from graphic elements.

I've been searching for a complete & complex example application with
good design, from which I could learn & realize my mistakes, but
couldn't find any through google so far...

would anyone know of such app ? maybe an open source project ?

thanks for any info you might contribute...
