I wonder whether  you have seen a video tape like the one I saw  last week
about the life of the surrealist painter Max Ernst accompanied by Stravinsky's

music as background.
Moreover I wonder whether you have suffered from strong hallucinations (visual

and auditive)
like the ones  I had from June 1976 until February 1987  while I was
attempting
to overthrown the inertia of the educational system to pursue faithfully
the suggestions of my inner voice. I could not look for a Brazilian
psychiatrist
I would run risk of having part of my brain extracted!!!! And could not take
any medicine, I  am vegetarian and a simple aspirine put my brain anesthesized

for several hours!
If you have, I am sure modern and contemporary music should sound as  freedom
and delight to release one's inner pent-up emotions.
We artists say that the only dictators mankind should have, are musicians!
So  the angels of music is the voice of God! How God created the world?
Through a Word!
In the beginning  was the Word, and the Word was with God, and the Word
was God. All things were made by Him and without Him was not anything
made that was made. In Him was life; and the life  was the light of men. And
the light shineth in darkness: and the darkness comprehended it not.
Imagine if we could reach that level for creating artefacts on earth!

Well when one has not studied semiotics and hermeneutics,
this statement looks like precise.
Semioticists state " the task of the semioticist is not simply to describe
a system of expression, but to discover which systems of expression in
general are possible as expressions for a given system of content
and reciprocally.
Computer scientists have been recognizing a software is a sort of
art, hence architecture is an art..Art has an hermeneutic nature...
I mean art has the nature of conversation, play,  experience,  the
structure of the question and so on...All these mechanisms have
a serious nature, so serious they do not depend on the players,
or the persons engaged in these activities...

In agree. According to Dietmar Sch├╝tz and Frank Buschmann's tutorial
in Pattern Oriented Software Architecture ECOOP'97 Finland we gave
pattern categories:
Architectural patterns: express fundamental structural organizations
on system level.
-layers
- pipes and filters
- Blackboard
Broker
- Model-View-Controller
- Presentation -Abstraction -Control\
- Microkernel
- Reflection

Design Patterns: provide a scheme for refining subsystems or
components of a software system, or the relationships between
them.

from the GoF....

The modern development environments have focused on
establishing new architectures, which could be supportive
of an explorative, interactive and iterative program
development process.

There are four essential professionals involved  in the exercise of good
architecture:
- the industrial designer
- the architect (designer)
- the structural engineer
- the builder

Well  Bruno Zevi states "The essence of architecture.. does not
lie in the material limitation to spatial freedom, but in the manner
how the space is structured in a meaningful form through this
process of limitation...

A contemporary architect cannot disregard how to integrate
environmental comfort, structural and building systems,
activities (the layout of furniture respecting the
ecology of human behaviour (ergonomically and anthropometrically)
as a unity in a seamless process...The same we must say
about the other professionals.

For the modern artist, the machine or the technological dimensiom
would free mankind from slavery, would free mankind to take
profit of the really human potentials.

When I finished my ecodesign model in 1988 (which was considered
a work of doctoral level) I had to face the need to implement it.
Of course if I had engaged in practices like programming in Pascal
C, Prolog and even Lisp was not tasteful to me , I would kill
my creative potentials.
This is what the CAD group from GSAUP UCLA offered. There was
even a PHD in computer science in Spain based in Pascal and so on
and was at Architectural Faculty Sydney.
I would prefer to starve and stay in Brazil than to do this.
I kept faithful to the hermeneutic nature of my ecodesign model
and soon I discovered OO programming till the glorious
moment I was introduced to Self (1996).
Now I say Kansas is musical...so I can turn the act of
building sustainable cities into a hymn of worship to the Creator..
I mean working together in architecture may mimick the nature of
a symphony thanks to wise technology. Indeed Scandinavians
say there is no social segregation...There is lack of scientific
and technological knowledge to allow each human being to
enjoy a high quality of life.

It would be desirable that programmers  that realize a software is
also art, should be trained in art too. This is the essence of my recent
post-dcotorate  report.

The aim of open computational systems is to overthrow segregation...The
marriage of  reflexive metaarchitectures and OO promise to change
radically the way of thinking, organizing implementing and using
programming languages and environments.
Self/R from Jecel wants to follow this trend.

This I let for the experts to add comments.
