It can be animated with only 11 more bytes

light_source{1 4}
camera{location 1 look_at 0}
sphere{0,2 pigment{rgb 1}scale<1,1,3e-7+clock*1e-9>}

Make clock change by integer amounts (as in 1,2,3 or 1001, 1002, 1003) for the animation to be obvious at first look. Change the 1e-9 as appropriate.

This is called the third competition but I haven't found any previous results on the website so I don't know if this has been used before.
