[Rhapso]

I have a hand sculpted human skull I use for this purpose. It makes me feel all cool and evil. But seriously, the act of formulating a thorough explanation of a problem often leads to its solution. Try it, if inanimate objects are not your thing, get a patient significant other or friend (or maybe another programmer if you are lucky) who will let you half explain a problem until you have that epiphany and run off to fix it.
