A few years ago I saw an air plant necklace in a magazine. Silverish metal, living plants, anyone remember it?
I think I saw it in Garden Design. It was link chain, I think, with small metal containers (not glass) for the tiny plants. I remember that you stored it in a shallow dish of water when not wearing it.
Was it Paula Hayes? http://www.paulahayes.com/living_necklaces/gallery.php?g=10
We did a blog post about her awesome terrariums at MoMA a few weeks ago: http://www.gardendesign.com/blogs/editors-blog/paula-hayess-art-terrariums-moma
