Fast Company has a nice-to-look-at and informative "trend watch" photo essay about large-scale installation art. I like Anish Kapoor's tower of shiny metal balls at London's Royal Academy of Arts best. (I love his famous shiny metal bean in Chicago.)
Not so much Mel Kendrick's zebra-striped totems in Madison Square Park.
As far as art in Madison Square Park goes, I miss Roxy Paine's shiny metal trees.
This may be because I am a magpie. (I wonder if I would pass the mirror test?) Which makes it kind of surprising that I've never cared for Mase.
We Chicagoans are always fans of shiny metal objects and gubernatorial corruption.
Roxy Paine's shiny metal trees are now on the roof of the Met:

Anish Kapoor's sculptures look like the sterling silver charm necklaces from Tiffany's that all the boys used to buy for their girlfriends in high school.
