I usually understand my own symbolism, but I am open to other people interpreting it. For example, I use the recurring imagery of glass, such as in windows and mirrors, to make the point that my character sometimes feels as if he's trapped in a glass cage, looking out from a world he's not a part of.
(Ohmigawd it's a Vash!)
That's a nifty concept. I would be interested in reading something like that.
I'm with Icehawk here. The capacity for readers to blow your "intended" symbolism out the window is insane. What you intend is not necessarily what they'll get out of your writing. But that's not necessarily a bad thing, in my opinion.
But in terms of things I've toyed with lately, birds are probably the biggest right now. It's to be expected--the protagonist is from a nation that worships birds as gods, so naturally she's going to see symbols and heavenly influence based on the presence of birds or feathers. At the same time, what birds represent in-world are not exactly the same as their various "meaning" in the real world. Nor do I always use the most common/well recognized meanings (the swan is my biggest offender. Happy day! You saw the bird of love and grace! Except you didn't. You saw the bird associated with foresight in regards to death and hypocrisy. Don't that just suck?) So while the character interprets one thing, I'm working on another.
But other than that, I don't normally try to incorporate any kind of symbolism into my work. Sometimes my IJ or my beta-readers will pick up on something and then I might try to work with it, but for the most part it's unintentional.
Unless a character associating an item with a symbolic meaning of his or her own counts?
