Heya,

Which you can use from Guile-Clutter [1], a must. I maintain a personal toolbox,
called grip, which as some guile-clutter examples [2], some using cairo (the
spline, the clock ...)

I'm working on Guile-CV, a computer vision functional programming library for Guile,
which provides a high level API. I uploaded a tarball here (for GNU evaluators),
here:

http://download.savannah.gnu.org/releases/grip/guile-cv/guile-cv-0.1.0.tar.gz
http://download.savannah.gnu.org/releases/grip/guile-cv/guile-cv-0.1.0.tar.gz.sig

[ GPG Key: A3057AD7
[ gpg --keyserver keys.gnupg.net --recv-keys A3057AD7

[ I will upload a new version within the next few days, stay tuned...

Chers,
David

Thanks, David, I'll take a look at those :)
