It's my favorite shortcut for generating a plane curve's normals. Cross[] actually has a nice hierarchy: one argument for two dimensions, two arguments for three dimensions (i.e. the conventional one), three arguments for four dimensions... all based on the Hodge star.

@J.M. Wow, there is a single argument variant of Cross?! Oo

Equivalent, but slightly shorter: ν = t \[Function] Evaluate[Cross[Normalize[γ'[t]]]];.
