  It is an open question whether right-angled Coxeter groups have unique
group-equivariant visual boundaries. Croke and Kleiner present a right-angled
Artin group with more than one visual boundary. In this paper we present a
right-angled Coxeter group with non-unique equivariant visual boundary. The
main theorem is that if right-angled Coxeter groups act geometrically on a
Croke-Kleiner spaces, then the local angles in those spaces all have to be
right angles. We present a specific right-angled Coxeter group with non-unique
equivariant visual boundary. However, we conjecture that the right an- gled
Coxeter groups that can act geometrically on a given CAT(0) space are far from
unique.
