You can probably make your own facsimile or similar structure for less than 1 million. Those orbs look like the dollar planters at the dollar+ stores....I am sure you can find a custom glazer who can mimic the cerulean blue glass and smooth it out and stretch it for a few grand. If I wanted to tee off the billionaire, I would put up three 15 foot tall flagpoles which would black the view of the artwork with different flags rotating on and off and make sure the pulleys squeaked and the flags made lots of noise flapping in the breeze.
You have presented two great ideas!!
The wealthier folks sometimes lose all aspect of dealing with other folks. So many of the wealthier seem to believe money really does solve all things.
Money makes life easier for many and terrible for those who cannot handle it or are hurt by those who relish using their wealth to harm others. Like anything in life moderation is a good thing.....when money is considered....
