“Anselm Kiefer: Uraeus”

Nietzsche’s notions about the will to power, the death of God and the Übermensch or Superman provide partial inspiration for Kiefer’s Uraeus, his first-ever public art commission in the United States. Standing 20-feet tall, the work features some of the German artist’s signature materials (lead sheeting) and motifs (books, wings) in a paean to classical mythology. Rockefeller Center. Through July 22.

Playlab, Inc., “Grown Up Flowers”

Although you might understandably confuse “Grown Up Flowers” with the work of Jeff Koons, these momumental blossoms are actual inflatables instead of renderings of the same in stainless steel. Their puffy presence along Park Avenue gives midtown a much-needed jolt of playfulness. Park Avenue between 44th and 55th Sts. Through July 2018.

Erwin Wurm, Hot Dog Bus

A sort of arty version of the Oscar Mayer Wienermobile, this customized VW bus has been repurposed as interactive public art installation that will be giving out free hot dogs all summer. The handiwork of absurdist Austrian conceptualist Erwin Wurm, Hot Dog Bus offers a humorous jibe at consumerism while saluting one of NYC’s signature foods. Brooklyn Bridge Park, Brooklyn. Through Aug 26.

Virginia Overton, “Built”

Overton’s ensemble of heavy-metal sculptures along the Long Island City waterfront includes a monumental diamond made of steel girders and a pick-up truck with a functional fountain burbling in back. Socrates Sculpture Park, Queens. Through Sept 3.

“Diana Al-Hadid: Delirious Matter”

This group of six new sculptures by the Syrian-born Brooklyn artist Diana Al-Hadid represents the artist’s first major public art project and features her signature blend of figurative and architectural elements that seem to dissolve into thin air. Made of materials like gypsum and fiberglass, her apparitions draw upon the ancient past for inspiration while evoking a vision that combines sci-fi with spiritualism. Madison Square Park. Through Sept 3.

Steinunn Thorarinsdottir, “Armors”

Icelandic artist Thorarinsdottir goes medieval at the Cloisters with her surreal sculptural installation. It features three different pairings of an androgynous figure with a suit of armor from the Metropolitan Museum’s collection that had been 3D scanned before it was fabricated in aluminum. The unsuited figure, meanwhile, is made from a body cast of the artist’s son wrapped in bandages. Cloisters Lawn, Fort Tyron Park. Through Sept 13.

Kang Muxiang, “Rebirth”

Seven monumental sculptures have taken up residence along Garment District pedestrian plaza in midtown courtesy Taiwanese artist Kang Muxiang, who fashioned the embryonic forms out of recycled elevator cables salvaged from Taipei 101, which is currently the ninth tallest building in the world. Broadway between 36th and 39th Sts. Through Sept 15.

“Yinka Shonibare MBE: Wind Sculpture (SG) I”

British-Nigerian artist Shonibare is adding additional color to Central Park with an undulating Fiberglass sculpture covered in bold shapes sporting a palette of bright hues.

Through Oct 14.

“The Roof Garden Commission: Huma Bhabha, We Come in Peace”

The handiwork of Huma Bhabha, a Pakistani-American sculptor based in Poughkeepsie, “We Come in Peace” depicts what could be described as a first contact scenario featuring two statues: A standing figure resembling the alien from Predator, and another lying prostrate before it. It’s not clear whether the latter is human, since it has a tail and is cloaked in a shroud, but in any case, the ensemble appears on the Met rooftop as if it had just landed from outer space. The Metropolitan Museum of Art. Through Oct 28.

Jacob Hashimoto, “Never Comes Tomorrow” and “The Eclipse”
