Video length?
Background?
Visual aids?
Presenter?

You're at the part where things get interesting - and remarkably useful - if you
stick with it and follow through far enough.

I can attest that there are an amazing number of things that can be done with
the simplest of "tricks" - just using vcross, vdot, matrix determinants,
eigenvalues, and vector swizzling.

And while that may all sound complicated and "out of reach" - the point is that
you don't have to understand a damned thing about how any of it is "done" - you
just need to understand the significance of the result.   What it means.

And then you can go on to code some pretty amazing stuff, that's easy to write
(as a result of knowing the "tricks"), and is FAST - compared to the usual "I'm
going to write my code in the exact same way as I went about figuring this out
the long way" that we all do so often.
