Thanks that's great! The pretty printing didn't seem to do much in my native Python shell. I should probably be using IPython and then isympy but I think I prefer to stick to the basics since a Windows-based worksheet is sure to skew things otherwise!
Good idea about links to further work. Yes, if there's feedback, or I do more work on this I will certainly look into offering something to the SymPy outreach effort!
