A collection of
stray socks bundled together in the hope that their partners will one day spontaneously rematerialise. The
name derives from the fact that the loose end of each sock emerges like a tentacle from the body of a cephalopod.
The preponderance of unattached socklings is now known to be an effect of quantum
physics. The uncertainty about the fate of the other socks is known as the Uncertainty Principle.
