Query: Crystalline Evolutions in Chessboard-like Microstructures   We describe the macroscopic behavior of evolutions by crystalline curvature
of planar sets in a chessboard--like medium, modeled by a periodic forcing
term. We show that the underlying microstructure may produce both pinning and
confinement effects on the geometric motion.
