Thanks so much for writing this-- I saw "History of the Main Complaint" at the MCA in Chicago (one of the illustrated movies) and it was fantastic.

Kentridge's stereoscope piece Etant Donnes gives a nod to Duchamp, but it is clearly a reference to Durer's "Artist drawing a Reclining Woman" done in 1538, a pivotal piece in the study of perspective. Kentridge's pose of the artist looking through a window grid between the legs of the woman whom he is drawing on a grided paper (in Durer's engraving she has a bit of cloth there) is identical to the 16th century work.
