You know, a case could be made that a spreadhseet *is* a visual programming
language.

I think visual languages would be most closely related to the dataflow
metaphor. That is the most dimensionally ordered one. Think of building
UNIX shell programs by fitting together pipes to little tanks called
"awk" and "sed"...

But visual programming generally seems to be concentrated on database
type things, expressed by turning a relation into a tree. The problem is
that this tree is essentially linear: people don't need the extra
dimension to comprehend it. In fact the 2-d representation conflicts
with the 1-d representation of trees we're taught in school: algebraic
notation.

Perhaps a visual shell for UNIX would be a useful place to start.
