What goes together better than titanium panels and razor-sharp edges than hundreds of small young dumb human beings engaging in running, skipping, falling and playing? Nothing! Or so thinks Mayor Bloomberg and the Battery Conservancy, who announced that Frank Gehry, the world's trickiest one trick pony, will be bestowing his whimsical architectural derring-do on a one-acre playground in Battery Park. Seriously, I used to babysit in TriBeCa and those kids will injure themselves on like, grass. They're rich but lack motor skills. But hey, it's TriBeCa, the land where parents barely even notice as their kids skid across their loft's whitewashed hardwood floors and slam into the Mies Van Der Rohe daybed with a impish sickening thud before returning to peruse the latest issue of Architectural Digest.
