Who *actually* understood Quaternions for real? I can work with them, but I never quite really understood them.
Can someone point me to a good resource that explain them, well, intuitively?
@pythno I think Freya did a video on them, after everybody kept asking.
Why can't you multiply vectors?

@pythno yep, that's the one
@sol_hsa Just came to back to say thanks again. Watched it and both of her videos on the topic are super good. Got me closer than ever. Just going to give them a rewatch. I like that she does the x->y->z->x cycle and explicitly calling it the zx plane. That alone is very useful in the field. Also I agree with her that CCW and CW don't really make too much sense.
