Anthropologie used vertical straws stuck together in their jewelry display. Saw it today, but I think they've had it there for a while. Reason why I am posting is because a few weeks ago I bumped into these old photos from '05 I snuck at the Tara Donovan exhibit at Ace Gallery in LA. Interesting when you know where inspiration could've come from.
This is a wall of horizontally stacked straws.
All those white circles - styrofoam cups! Notice the scale. Two years later, I still remember how amazed we were.
