KNOTSBAG 2.1

KnotsBag is vector graphics software based on graphs. With KnotsBag you can design knotwork (or other drawings) very easily  and very quickly.  There are so many parameters for the generated Bézier curves that it is possible to create many other designs as well as knotwork!
I wanted to develop this software after reading the paper "Celtic knotwork" of Christian MERCAT, Scientific American "Exotic mathematics", April 2005.  I do recommend visiting his website :  http://www.entrelacs.net
