About

My main interest has been visual results, and that tends to be a primary criterion for deciding whether a program is working correctly or not. While I would like the programs to work as well as possible they aren't meant to be considered as producing careful numerical solutions.

I wrote the programs as I went along and that is reflected in the (lack of) design of the project. For general release I have, however, made an effort to tidy the code and build process, reduce code duplication, and make the programs behave consistently.

I have made the programs available in the hope that they will be of interest to other people, maybe useful, but mostly that they will be fun to play with.
