  We explore the limit set of a particular spherical CR uniformization of a
cusped hyperbolic manifold. We prove that the limit set is the closure of a
countable union of $\mathbb{R}$-circles, is connected, and contains a Hopf link
with three components; we also show that the fundamental group of its
complement in $S^3$ is not finitely generated. Additionally, we prove that
rank-one spherical CR cusps are quotients of horotubes.
