Mank- your explanation sounds fine on a macroscopic (ie, "big") level, but you're oversimplifying. It'd be a bit like painting over a stencil but only using one atom of paint- you can't permanently change the shape of an atom so whatever your stencil looks like you'll end up with a single spherical atom when you take it away.

But of course, as others have pointed out, it isn't like that atall on a microscopic level because of the wave-particle duality of light. I'm more engineer than physicist, but Foof's "working backwards" idea and David's "Young's slits" analogy seem plausible to me.
