Gimme Shelter

On the edge of David Lam Park on the seawall are four of these concrete and glass creations. They look like a cross between a tree and an oversized patio umbrella. I'm not sure if they're meant to be public art, actual shelter from the elements, or some combination of the two, but I liked the geometric feel as I pointed my camera up through them to the sky.

Post title, of course, from the iconic Rolling Stones song.
