Chocolate was what the artworld wanted then. Color on your walls. "Chocolate bars" rife for inference, wordplay, poetical inkblots for the viewer to see what they wanted. Suggestive and blank. A Rorschach lure, and trap. Now here they becomes a silver mirror. Now here we've got holes cut out for white "spectacles," peeping for a history of scientific racism, for our gawking and calling it erudition. Which is another apt metaphor for recent turns in art. Never seeing the white for the walls. Turn around, look inward, calls coming from inside the house, etc.
