Lee, if you are looking for a classroom teacher to try out pynguin in the classroom, sign me up!  I'll have it installed in my lab on Thursday, when I return, in any case.  It rocks!

Thanks! Glad to hear it!

Now a question:  how difficult would it be to get pynguin to output svg images?

Turns out with QGraphicsScene it's actually pretty easy. Try replacing the MainWindow.export() method in mw.py with this:     def export(self):         for pynguin in self.pynguins:             pynguin.gitem.hide()         from PyQt4 import QtSvg         svgen = QtSvg.QSvgGenerator()         svgen.setFileName('test.svg')         svgen.setSize(QtCore.QSize(500, 500))         svgen.setViewBox(QtCore.QRect(-250, -250, 500, 500))         svgen.setTitle('Test SVG Output')         svgen.setDescription('PyQt SVG Generator')         painter = QtGui.QPainter(svgen)         self.scene.render(painter)         painter.end()         for pynguin in self.pynguins:             pynguin.gitem.show() It's just a proof-of-concept, but it definitely works. Thanks for the suggestion. I will look at adding that option for the next release.
