I have used Google to investigate how things are with constructed languages. Apart from the one(s) developed by Tolkien for the Lord of the Rings and old attempts at international languages like Esperanto, there doesn't seem to be much going on in recent times. 'WiseGeek' is a website which has a good summary of what constructed languages are about. I haven't yet registered to be able to contribute on this site, but am still trying. 'Syai' is a language linked to a fictional world and culture, quite well developed in itself. The Syai world has a sustainable, small-growth stable civilization with a culture of individualized well-being. To me it suggests the direction in which this planet's human civilization might progress to avoid disaster. "Utopia is a beacon on a hill that can never be climbed", but its light can nevertheless show up more clearly the alternative ways. The picture contains an example of hand-written Syia script. The printed script is available but so far only on my personal computer.
