How do you visualize quantum spin?

[Scott99]

I have previously read that the spin of a particle is comparable to angular momentum of a system or object on the macroscopic level. However, the quantum world is much different and all I can imagine is a minuscule ball rotating on it's axis.

You really should not be imagining that. The spin is an intrinsic property of a quantum particle and a quantum particle behaves nothing like a minuscule ball. The name "particle" is there for historical reasons.
