textured spline curves

Looking at “The Csound Book” cover on my desk I got the idea to do something
similar in Jitter. To me it looks like symbols that are mapped/ warped using
splines. Any ideas on how to accomplish a similar effect in Jitter ogl?

Hi Thijs,
This patch might get you started. Don’t be surprised to see some
version of this in the Jitter Recipes in the future.
