A web search on "Pythagorean Tree" and "Sketchpad" produces quite a few hits,
including a set of directions David Chandler gave several years ago in this very
forum:

There's a presentation by Nick Jackiw from an Ontario conference a few years
back: www.osapac.org/dbOESS/OESSResourceDownload.asp?ID=251

There are also a couple of commercial sources. (Full disclosure: I work for Key
Curriculum Press.)

The folks at Atomic Learning have put together a movie (though you have to
subscribe): http://movies.atomiclearning.com/uk/geomsketch_mac/

And a nicely colored tree is the subject of one of the activities in Key's
activity book Pythagoras Plugged In (though you have to buy it):
