Selecting Objects

Anyone know a good way to show a highlighted object? Right now when an object is selected I just scale it a little bigger and rerender it transparent yellow. It looks like crap. If it’s a 2d object it just shows it parrallel and looks bad, if 3d it doesn’t look right either. I am imajining a nice glow around the object when I select it.

low-intensity ambient light from core of object looks nice
