OK, I'm trying again, as I didn't get any understandable comment on my earlier comment.In 1987 I saw the center part of this picture in a kind of "revelation" which lasted for around 3 minutes under heavy cold sweat and convulsions. Then in 2009 I recognized it, and exactly that part, which is on the front page of Keith Curtis book "After The Software Wars".I wonder, if you possibly can say what is your inspiration for this picture. Did you possibly have a similar kind of revelation?After I saw that picture, although with golden sky, not blue, this picture has actually the exact blue color of the wallpaper I saw it on, in our house then, I instantly turned from an "agnostic" to a "convinced" as I understood that we live in a virtual reality.I was also able to write up a missing school report to get my exam, so I could later start my PhD program which I was inspired to do after seeing that picture.My school report describes the future technical and social development from 1987 to 2037, so far correct.What I've never really understood is what that portal means. First the portal is on the left (at least on the cropped version I saw), and I'm a left-libertarian where "left" means "true". I have two ideas:1. refer to the web portal I'm developing inspired by seeing that picture as well as the research program I was inspired to start which enabled me to get the skills needed to develop such a web portal (which will abolish all kinds of artificial scarcity to lift humanity towards the future).2. As you have another version of this, animated, denoted CLOUD city which gives synchronistic vibes towards a hobby project me and some friends had in the late 80's, to develop a generic crunching add on to any PC, denoted CLOUDComputer Lönnerberg Orre Ullén Djurfeldtbased upon the Transputer, which was unfortunately killed when Thomson purchased Inmosmy idea is that the portal would be an electromagnetic acceleration/deceleration unit for levitating sky-trains which go between the CLOUD cities.To implement such CLOUD cities could be doable with a solution I found, but not yet thoroughly tested, a physical problem I've pondered over since I was 12, but got an idea to recently when I was out driving. Then tested in a simple physics simulator as soon as I was back to office. It seems to work.Another thing, how old is this picture? I find it interesting that the middle tower actually resembles the new One World Trade center.
