Since performance artist Marni Kotak gave birth at Brooklyn’s Microscope Gallery, she’s been back showing off Baby X a.k.a. Ajax. He’s the “highest form of art” and you can see him plopping into a birthing pool via mommy’s new video installation. Twenty “sincerely interested” and “really supportive” visitors are coming over a day to look at it, look at it!

That’s one way to grow a family…
