Sperone Westwater calls it Light Ballet on Wheels, 1965. Sure.
It's hard to tell from the microfilm, but a photospread of artist-made household objects in the New York Times Magazine ["They Call It Art," (-ouch), Sept. 25, 1966] sure mentions that "15. Black metal drum table by Otto Piene has a glass top and a base that projects light patterns on the ceiling. From Howard Wise." Just wonderin'.
