You are correct, Bill, but one can also go blind using that method

That's not a unit sphere. It's a sphere of unit radius.

In POV speak
y = <0,1,0>
so
y*0.5 = <0,1,0>*0.5 = <0,0.5,0>
also .5 = 0.5

Should you get into animation, that is the only way to do it.
Just make variables rather than absolutes for everything that
moves.

Well, the sphere with unit radius is commonly referred to as the unit
sphere.

That's why I make all my spheres with a 0.5 radius, so they will be more
reasonably called 'unit' spheres. So that like a unit box, if I copy one
exactly one unit away, they will just touch.

Why, do you use box { <2+7/8,5+1/2...?
