I'm developing an OSS modular framework which has similarities to http://www.filterforge.com/features/editor.html but my current GUI is *really* ugly: http://www.openblackbox.net/Photoalbum_contents.aspx?Albumid=1 I'd prefer focusing on the core functionality rather than the GUI at this stage, so it would be great if I could find a library that helps me out with the boxes/pins/connections representation. Any ideas? Thanks.
