I'll be talking on J to a meetup here in New York this coming Tuesday - http://www.meetup.com/7-Languages-in-7-Months-NYC/ - so I've been watching the "fork examples" discussion w/some interest.
I did a dry run of my talk at NYCJUG this past Tuesday and, at that time, I was looking to build up to a final, mind-blowing example like the Newton-Raphson iterator, but now am thinking that that's too "tricky" and what I'd really like to do is go into detail on some simpler examples. Joe Bogner's interest in the parenthesis-nesting idiom reminded me of how innovative the array approach still is, so I'm definitely using that one. David Lambert, who was at the NYCJUG meeting has also given me a couple of good ideas since then but I'm interested in anyone else's favorite J idiom - "Jems" as Dan would have it - that illustrate the usefulness of array thinking.
