I am please to announce the distribution of DrGeoII, an interactive geometry framework for Squeak, under the LGPL
http://www.squeaksource.com/DrGeoII.html
DrGeoII is roughly based on previous DrGeo (http://www.ofset.org/drgeo)
It is far to be finished, but it is already in a quite well polished and usable state.
