Query: Cohomology of the Pinwheel Tiling   We provide a computation of the cohomology of the Pinwheel tiling using the
Anderson-Putnam complex. A border forcing version of the Pinwheel tiling is
constructed that allows an explicit construction of the complex for the
quotient of the continuous hull by the circle. The final result is given using
a spectral sequence argument of Barge, Diamond, Hunton, and Sadun.
