I found that fabulous contemporary organic chair by driftwood and plexiglass in my favorite freshome.
The Bare Bones Ghost Chair is a modern classic. Six beautifully worn pieces of driftwood stoutly suspend thick slabs of translucent acrylic sheet forming this remarkable chair. Minimal and ultra modern the Bare Bones bridges a divide between the natural and the manmade. While visually light, the chair is actually fairly heavy due to weight of the acrylic.
It cost $1,300.00 USD and you can find it on Etsy.
