maybe smb knows of similar initiatives ?
googling around found http://www.python-visual-sandbox.de/ another thing which I am curiuos about -- visualization: python is quite visual itself, but for CS intro its quite common to use flowcharts there's nice tool for two-way software Visustin (free demo) http://www.aivosto.com/visustin/sample/gcd-python.html one way: weird flowchart -> py (opensource) http://www.pygame.org/project/355/ also something similar to flowcharts - Vision (seems kind of opensource) http://mgltools.scripps.edu/packages/vision does anybody know of py -> flowchart (opensource)? I imagine it could be done with ast module similary as http://blog.prashanthellina.com/2007/11/14/generating-call-graphs-for-unders... or http://pycallgraph.slowchop.com/
