The new building sticks out over the Boardwalk, jutting toward the water, its facade wrapped in shimmery aluminum panels that move, like schools of fish, with the ocean breeze. The rippling panels join the clattery Cyclone, screaming teenagers, scent of suntan lotion and swarms of sea gulls picking at scraps of hot dog buns.

Coney Island’s latest attraction, “Ocean Wonders: Sharks!,” opens Saturday at the New York Aquarium. Go see it. It’s edifying and fun, an ideal excuse, if you should need one, to grab the kids and head for the beach — and it also happens to illustrate the difference architecture makes, in this case to residents in one of the city’s most underserved communities and to a neighborhood of honky-tonk amusement parks and oceanfront.
