Notice that no two rings are linked, yet all 3 rings are linked.
You could even use this to represent a proton - the rings being the 3 quarks that make up a proton.
This model even shows the famous "asymptotic freedom" and "confinement" of bound quarks. When the rings are very close together you can move them around as if they were free (asymptotic freedom), but when you try to pull them apart a strong force appears to stop you (confinement).
Speaking of interesting topology I wonder what would happen if you replaced each ring with a Mobius strip?
