“Fake” Borromean rings
At first sight, the figure seems to represent Borromean rings: instead, if we observe it more closely, we realize that the red circumpherence can be unthread from the other two, which are indeed linked together. See the interactive animation Borromean and non-Borromean rings to understand the difference.
