Dirac's belt trick models the behaviour of spin 1/2 particles.
When turning the end of the belt (the particle) by 4 pi,
the belt can be untwisted even while keeping the particle fixed.
Is there an analogous trick for spin 3/2? It seems that this would
imply rotations by 2 pi/3. What object would one have to take
(instead of the belt) to get a "spin 3/2 trick"?

Could you explain this trick in more details? Do you also happen to
know the trick for spin 2 particles?
