It feels ridiculous to even ask this after all these years...but here goes:

I understand the effect the shape of the aperture has on lens flares...But does it in fact affect -more- than just that?

Consider an 8mm camera that has a 5-sided aperture that creates the usual five side lens flares in photographs. Can the shape of the aperture ever make the light source itself take on a 5-sided outline? I realize that lens flares are caused by pointing the camera too far toward a very bright source or even catching the light source in the frame, and the lens flares are the result of internal reflections -inside- the camera lens. But is there any possible way that the shape of the aperture could somehow cause the light source to appear as 5-sided when it's caught in the image.

I'd appreciate any expert opinions on this. (..man, I must be getting old :/ )

Yes, if the light source is not in focus -- assume the light source is part of a substantially out of focus background.
 
This page has some interesting examples.
 
A few of my own using cut shapes in paper masks for the aperture, to give shape to out of focus highlights

That is clever, and a great way to illustrate flares.
 

I have to love the Jag hood ornament since I own one! Completely irrelevant to the topic, but I had to mention it! :chuncky:
