It's a nice example, thanks.
Only ... well, I don't want to demean your work and effort and it's more of a general observation but ...
It would be nice if example authors added a small write-up explaining how they went about to write them and why, what pitfalls and shortcomings they found and how they overcame them, etc.
Kind of, say, a small "tutorial" about the program
and the programming process; it would make the examples much more useful.
IMHO, of course
