Leon Reid IV, a 30s-something Brooklyn artist, wants to install a giant spider on the cables of the Brooklyn Bridge in time for Halloween 2014.

“A Spider lurks in Brooklyn” (Leon Reid IV)

Reid was inspired by the cable elements of the famed landmark which could resemble a spider’s web. He’s calling his vision “A Spider Lurks in Brooklyn,” and is now raising the estimated $800,000 for the project and seeking official approval.

The spider would be 60 feet long, 30 feet wide and about 15 feet tall, resembling the huge balloons of the Macy’s Thanksgiving Day parade.

Public art used to be the quiet and stunning sculptures of Alexander Calder. But lately, many projects have different components. A couple of years ago in New York, there were “waterfalls” up and down the East River. In Washington, starting this week, the D.C. Commission on the Arts and Humanities is sponsoring a citywide public art project, called “5X5” that has interactives, sound and shapes in 25 installations.
