Tiny vases were suspended on transparent guide wires and the flowers and the water in each vase, of different colors, depicted the Earth from the top of the mountains (white flowers: snow) sloping down to the ocean (bright blue flowers.)

The message seemed to be that the majesty of the Earth, from mountain tops to ocean shores, contrasts sharply with its fragility, represented by the tiny vases, the guide wires and the small flowers.

I might be making this up, but that is what the display said to me.
