Look!: Oversized Ribbed Pendants

We came across these oversized pendants in a shop window on Rue Sainte-Catherine yesterday. They're high on volume, yet because of their caged rib design they use little material...

We could definitely imagine DIY'ing something similar to create an oversized pendant at home. We almost think these were DIY'ed by the window display designer at the clothing store where we saw them. If they're mass-produced somewhere, we have never seen them. These would be so fun to make because you can choose a rib shape, repeat it, and create such a variety of volumes!
The fixtures remind us of the cagey structure of these round wire coffee tables.
