About this 3D model

This is a Python script that I've been working on for Blender, to generate 3D geometry based on bezier curves. My goal is to produce a variety of attractive and accurate Celtic knots and braids to use as artistic elements in my projects. I developed a customizable picture frame as a testbench for my work. You can use it as a stand-alone project to generate a picture frame with text (or without). http://www.thingiverse.com/thing:54020 Adding Celtic knot elements to that, my Celtic Picture Frame is an early result of these experiments. http://www.thingiverse.com/thing:55464 I have more ideas and enhancements that I hope to share later. The script is is in a usable state now, so give it a try! UPDATE: 2012 Mar 6 -- version 1.1. uploaded to fix bugs in the utility function ReadCurveControls()
