I was wondering if you planned to go to the Vermont Camp Shopbot. My wife and I are going, it's three hours north of where I live in Massachusetts.
I recently found a program called "Knotworker". I've been having a lot of fun creating Cetic Knots, it's very easy and very versatile. I've been able to use Inkscape to convert the Knot designs to a vector for V-Carving. I've carved a few designs and I like the results. This link will take you to the Knotworker site http://goldcup.cjb.net/index.htm
