Pretty cool. Pretty cool. I see that the the Seaside-Platform class category
is for relating Seaside to the underlying Smalltalk OS, which in this case
is Squeak. FillInTheBlankMorph, when called openInWorld, is a whole lot of
nothing. Just a blank pallet. I guess something is adding the text field and
the buttons.

This explains it. I'm very pleased to understand this. I thought the
Explorer was totally useless. I just didn't get it. It seems that instances
are invisible, and stay invisible. The only way you can "see" an instance is
with the Inspector or Explorer. You see, I thought that storing data in the
image meant that the image would WRITE IT OUT in a class method somewhere. I
thought it would produce a string that I could find with Command+Shift+E.
Frankly, I think I'm only starting to grok what an instance, object, and
class are. Oh, and I used to think morphs were stupid and waste of my time.
