Seems like the people flocking to the park are doing so out of some sort of need for a ritual. That's what these artists probably intended to facilitate in the first place.
Not sure about the color choice. It could represent the rising sun. The whole thing has an eastern vibe to it.
The way they describe it on their site
is with words like: "To experience the artwork, one immerses oneself into that environment"; "The Gates will be a golden ceiling creating warm shadows"; "The Gates will seem like a golden river appearing and disappearing"; "The luminous moving fabric will underline the organic design of the park."
From the Feb. 12th unveiling, it will be up until Feb. 28th.
In ancient times, a Chaldean Sabbat known as the Sabbatu was celebrated each year on this date.
On this day of the year, the Earth-Goddesses Ceres, Demeter, Gaia, Ge, and Mauri are honored by many Pagans and Wiccans around the world.
Also honored annually on this day is the ancient Pagan deity Zamyaz, who was worshipped and offered sacrifices by the ancient Chaldeans and Persians.
