A really cool light fixture, of course!
Designer Zach Kron created this curtain panel after extracting the fundamental design elements from the biological items and aggregating them into the above light fixture.
Zach's experimentation leads him to this tip:
If the geometry isn't thick enough, it crumbles, so doing fine details can be problematic. This can be a problem for doing railings, or other architectural details. But with doubly curved elements, the material is surprisingly strong.
Comments on Zach's post include requests for purchase of the fixture, but evidently he's having trouble getting it printed at Shapeways. Perhaps Ponoko could come to the rescue?
