These are the light fixtures in my apartment.  Which, in actuality, are hideous.  They're covered in about twenty layers of apartment-beige paint, and probably the paint is the only thing that's keeping them from falling apart.  But...viewed through the nifty little piece of holographic film left over from a science of light class, and--voila!  How pretty!  A classmate took an entire series of photos using this in all different types of light--I may have to give it a try.
