One of her most recognized interactive art pieces is "Baba Antropofágica." This piece was inspired by a dream that Clark had about an anonymous substance that streamed out from her mouth. This experience was not a pleasurable one for Clark. She viewed it as the vomiting of a lived experience that, in turn, was swallowed by others. In a sense, Clark seemed to view this atrocity as a way of displaying its freedom. One of Clark's (and for that matter, Oiticica) aims was to create art directed toward a larger world audience, drawing attention toward its social issues thus achieving a sense of cultural freedom. For her interactive art pieces, Clark always used inexpensive everyday objects. These objects would then only have significance if they came into direct contact with a participant's body.
