There is also http://sage.math.washington.edu/home/wdj/art/barnsley-fern-xmas4c.png It used GIMP, Inkscape (for the text) and this Sage code: http://sage.math.washington.edu/home/wdj/art/barnsley-fern.sage Also, there is http://sage.math.washington.edu/home/wdj/art/sierpinski-seasons-greetings-from-sage.png which used the Sage code http://sage.math.washington.edu/home/wdj/art/sierpinski-seasons-greetings.sage There is a letter-size "poster" in pdf at http://sage.math.washington.edu/home/wdj/art/seasons-greetings-sage.pdf and an A4 size one here: http://sage.math.washington.edu/home/wdj/art/seasons-greetings-sage-a4.pdf > > Funnily enough, this Christmas whimsy of mine highlighted one issue of > closed source mathematical applications that would be (at least > partially) solved with an open-source package.
