Hi, Guile has a tutorial written by Daniel Kraft, which uses Scheme to extend a C drawing process. It uses Gnuplot for the drawing, which is not GNU, and AFAIK not even free software. It would be better to use some other drawing library; for example, Cairo (http://cairographics.org/). The output would be to a png file instead of to the screen. Then we can also show a final stage of switching to use guile-cairo, and having no C program; and possibly even using a GTK+ surface instead of a PNG surface, which would allow the same program to show data to the screen instead of to a file.
What do people think? Is anyone interested in taking up this task? Andy -- http://wingolog.org/
