I love this combination of digital technology and the natural world that we've been seeing in recent years with interactive installations. This reminds me of Rain Room a bit. What I love about these types of installations is that the digital technology presents itself through not-your-typical digital interfaces, but familiar and naturally occurring things (water, plants, etc.) and is fueled directly by our physical participation and sensory expectations... the surprise of a moving flower or plant, ushering you through space, or the surprise of not getting wet in the rain.
It also reminds me of an installation I saw in Paris almost 20 years ago. I tried to look it up online and I can't find a record of it, so now I'm starting to think I'm making this up, or at least have an exaggerated memory of what I think I saw and heard.
BUT if I remember this correctly, there was a temporary installation outside the Centre Pompidou, a forest of Christmas trees. It was December, so not a surprising sight. But as you talked through, the trees whispered to you: Merry Christmas in different languages, ever so softly. It completely took me by surprise and I stood there in the trees for a while.
Talking trees. It was magical.
Which is sort of what I think walking through the Floating Flower Garden must feel like.
p.s. I'm really hoping someone can back me up on the existence of this Christmas tree installation and confirm that I was NOT hearing voices in my head back in 1997.
