Speaking of function args, this recent thread with another guy in Canada (you know him Andre?). :)
You'll find me writing about J going way back in this very archive, more recently joined by Ed Cherlin in singing its praises. For those of you looking for a way cool use of Python's ReportLab, I so far have permission to release this one example "PDF flipbook" showing how geometry concepts might be communicated using this simple animation technique: http://www.4dsolutions.net/presentations/pdf_animation_by_ron_resch.pdf I've been sharing this as a teaser with Software Association of Oregon as well, knowing Ron has a lot more where that came from (I'm suppose to download a half-gig PDF next time in Pauling House for a bored er board meeting).

Fuller on the last page (rarely cited by 1900s authors but a contemporary favorite in some circles), emerging links to Wolfram (whom Kenneth didn't get along with especially -- never met the man personally).
