Curved Space Explorer for Squeak 
The project introduces the Curved Space Explorer for Squeak project, known as CCSE by Krestianstvo SDK.
It is a Smalltalk port version of Curved Spaces, originally developed by Jeff Weeks (http://www.geometrygames.org) in C language. This Squeak version is derived from Krestianstvo SDK project's version, where Curved Space Explorer is collaborative in it's nature and available mainly for distributed computation. The aim of this project is to make Curved Space Explorer being available for the large Smalltalk audience and mainstream Squeak distribution, so that anybody interested could work with it.
