You have to come up with something pretty spectacular to
get astronomers to give up command line IDL programs with
15-20 positional parameters. (Something about "looking back
in time" and keywords only being invented in the past 50
years or something. I didn't really understand the arguments.)
So I hit on this idea of "smart" image objects that know
how to display themselves, set up their own coordinate systems
for data overlay, let you know if you clicked inside them, etc.
Surely that would interest an astronomer.

So, next thing you know, these images could make thumbnails
of themselves, and clone themselves, and do all manner of
neat and useful things, and these programs we were writing
just sort of took off on their own. I have to admit they
were as sophisticated as any I have ever written in an IDL
course. So much so, that I have really given some thought
the past couple of days to writing this all down and
making a book out of it.

Sometimes IDL just plain surprises you with how easy it
can be to do sophisticated things! :-)

Cheers,

David
