You're right... but I think I meant that's not how electrons/atoms are normally portrayed, so generally someone looking at the picture wouldn't instantly think that that was what it was (to me it looks like a kind of ball made up of 3 rings).

As far as I understand, it's impossible to ever tell where an electron is or where it's going to go, in relation to it's nucleus, so surely there can never really be a specefic way for the to line up in?

If you're going for the 'electon orbits' thing with the circles, you should check a reference. They don't line up that way usually. Also, the circles make it a little bit hard to discern the rat. I think there may be a better way to show the 'atomic rat' concept... perhaps consider having the circles go around him all different ways so none of them block out any part of him.
