I had been reading the book “Fractals: Endlessly Repeated Geometrical Figures” by Hans Lauwerier (Princeton University Press, 1991) and wanted to play with some of the BASIC programs listed in that book for generating images of fractals. I didn’t have a BASIC interpreter to run the programs, so I created a BASIC parser called basicfractalsvg to generate SVG images directly from the programs. You can download it here.
