Good point Steve, if you were to scale or rotate that sphere you would be doing
so with it already moved and can't go back without some extra transformations
done to reverse it.
Changes in a primitives location vector are fine if the primitives are never to
be changed thereafter, just not a good common practice I would think.

| Yes this should work fine, but personally I'd prefer
|
| sphere { <0,0,0>, .5
|          translate <clock*10,0,0>
|        }
|
| This will move the sphere from <0,0,0> to <10,0,0>.
