Tattoo Idea: Creativity Needed!

I don't have a ton of readers, but I've got a fair handful, some of whom are artists (Ahem, Marc.) I thought of an idea for a tattoo I would like to get. I want to get something that represents the Divine Spark, that notion that there is a little piece of God/Creator/Whatever in all of us. Problem is, I don't know what it should look like. Any ideas?
