Finally taken the plunge and have begun using a revision control system for BoxySeq source code. I've chosen to use http://github.com which uses the GIT revision control system (as used by the Linux kernel).
You can find BoxySeq at http://github.com/jwm-art-net/BoxySeq. Github also provides a basic WIKI for projects that use it, and at http://wiki.github.com/jwm-art-net/BoxySeq you will probably find the sanest write up yet explaining what BoxySeq is about.
BoxySeq is currently of little interest to end users, and almost everything about it is developer orientated at the moment. Here's another video showing what it will do so far: http://jwm-art.net/art/grid-2010-21-06.ogv(dead link)
