I actually remember seeing this on some future predicting TV episode back in 1996. I remember seeing 20-story orb network connected by rail transport in a triangle pyramid formation. Each orb was like a city zone e.g. commerce, industry, residential, etc. By 1996 standards, this thing seemed ridiculous and large. I mocked it at the age of 11. And my father yelled at me for being so ... pessimistic. Back then, the show said it would be built by 2005 in the middle of the waters. Always wondered what happened to this building and this plan.
