Who or what is Spinoza's god?

I believe that spinoza was the father of pantheism. In that, I believe that he speaks of God that IS EVERYTHING. There is no overbeing, or idea of God, for God is the idea and also the creator of the idea. I think it shares a bit with Taoism since Tao is unexplainable in it's complexity but is still as simple as water. Spinoza's God is everything, and everything is God (from building blocks of energy, to the most complex sentient beings).
