I hope someone could be interested in implementing semantic browser widget for KDE4 while playing with Qt4 drawing features... For example, similar to news.com's News Plasma.
Quite suitable complement for KDE4's search engines.
is saw a demo of this on MacOS in 1995... i guess there is truth in the saying that if you wait 10 years they will just recycle the technology ;) i think the big problem with it was that as the links piled up the views got way to hard to traverse. that being said if we stay aware of how these sort of interfaces scale, we may get it right this time.
Qanava (http://www.libqanava.org) might be a good start, even if, as a QCanvas based lib, it is not very qt4 friendly...
I've found following Java implementation (warning - Java applet): http://www.fxparlant.net/Special:Touchgraph -- drag the node.
Maybe it's good extension for KDissert's GUI?
