bspline-hack by John Cantrell
bspline-hack is an xscreensaver hack that draws b-splines in motion.
Maybe one day this will be included in xscreensaver, but until then:
tar -xzvf xscreensaver-4.xx.tar.gz
tar -xzvf bspline-hack
cp bspline-hack.c xscreensaver/hacks/glx
cp bspline-hack.config xscreensaver/hacks/config
cp particle.xpm xscreensaver/hacks/images
cp makefile.in.patch xscreensaver/hacks/glx
patch ./Makefile.in ./makefile.in.patch
This has been tested with xscreensaver-4.18 hopefully it will work with
other versions but I have not personally tested this.
Try a high level of curviness with -points, it looks pretty neat.
Well that is all and I hope you enjoy this simple program.
