  The phenomenon of convection is found in a wide variety of settings on
different scales -- from applications in the cooling technology of laptops to
heating water on a stove, and from the movement of ocean currents to describing
astrophysical events with the convective zones of stars. Given its importance
in these diverse areas, the process of convection has been the focus of many
research studies over the past two centuries. However, much less research has
been conducted on how the presence of an obstruction in the flow can impact
convection. In this work, we find that the presence of an obstruction can
greatly affect convection. We note occurrences where the presence of an
obstruction yields similar behavior to flow without an obstruction.
Additionally, we find cases with markedly different features in comparison to
their counterpart without an obstruction -- notably, exhibiting long-term
periodic behavior instead of achieving a constant steady-state, or the
formation of convection cells versus an absence of them.
