A tiling with infinite rotational symmetry, such as the Conway–
Radin Pinwheel Tiling, gives rise to a topological dynamical system to which
an etale equivalence relation is associated. A groupoid ´ C
∗
-algebra for a tiling
is produced and a separating dense set is exhibited in the C
∗
-algebra which
encodes the structure of the topological dynamical system. In the case of a
substitution tiling, natural subsets of this separating dense set are used to de-
fine an AT-subalgebra of the C
∗
-algebra. Finally our results are applied to the
Pinwheel Tiling.
