Well after trying the new version of Eclipse, I gotta say I'm pretty disappointed. The new features are cool and everything, but it's really unstable on my PC (openSuSE amd64). It's so unstable it's difficult to get any work done. I mean 3.2 crashed every now and again, but 3.3 crashes every 10 minutes.

Tried to start work on the 3d editor that will be used to construct worlds and models from meshes. I'm planning on using SWT (the crossplatform GUI that is supported by Eclipse) and JOGL for 3d rendering. SWT is pretty sweet for GUI's, for example check out:

Azureus
and
Vuze
