SET 26 is a Swiss design company that sells furniture shaped like letters from the Roman alphabet. Each letter costs about 1,500 Euros and has doors that open revealing shelves. They have a Konfigurator so you can see any combination of 5 letters in the available colours (like the GROCK above.)
I read about this in a strange online Facsimile Magazine while reading a reproduction of a 1970 Time Life Books’ Nature/Science Annual article on “Art’s New Ally – Science.” The article documents a number of technological arts projects including the Experiments in Arts and Technology (E.A.T.) cooperative founded by Billy Klüver and Robert Rauschenberg.
