an alpha release of Kmindmap for KDE 3 is now in the CVS repository. It does nothing usefull, but one can see and move blobs.
I have recently written a Homepage for Kmindmap. There's also an updated bin.
Kmindmap is just an other mindmapping tool. It has the nice feature that a pseudo physics simulation moves the treegraph around to keep it looking good. Besides the fact that this is really usefull, the simulation is fun to play with.
