Interesting to see what is possible – a lot more than I might have imagined.
I have sometimes thought that a good way for a user to learn Tinderbox would be to create a Tinderbox file about learning Tinderbx. And that leads me to think that it would be interesting to have a series of Tinderbox files at different stages of development. Instead of asking the student to deconstruct the file, it might be useful to see how an experienced user goes from the very first blank file and gradually builds in new elements. (Probably that is what you are planning.) The learner could then look at Tbx1, followed by Tbx2, Tbx3, etc., and see the building process at each stage, making comparisons between the files in sequence. I’m all in favour of small chunks, but I think that chaining them in sequence could be very powerful.
