How do you drive a vertical shaft with a horizontal motor mount?

I understand mitre gear, spiral gear and a worm drive. Is there another way?
I have been looking through several texts and am not having much luck. Is
there a way to do it with a chain? I cannot see a V-belt doing it. Some sort
of friction drive instead of gears? But how good is the power transmission
in such case?
There are special "3-D" chains that can do this. Belts are easy. See
if you can find a picture of a Corvair engine, the fan was run by a
right-angle belt drive. The generator was one of the pivot pulleys, the
other was an idler.
Try this, if hand-held cameras don't make you dizzy:
