Pyramid Gallery specializes in replicas of LeMarchand boxes, a European craze that took off in 1749 and is connected to the disappearances of “noteworthy individuals” who bought them. Created as one-of-a-kind puzzles by French sculptor/architect Philip LeMarchand, many of the boxes played music when opened, and this site provides historical anecdotes behind such designs as “The Threnody Configuration,” the “Jeremiah Enigma,” and the “Elysian Tetra Morph”. A great find for fans of Clive Barker..
