Tools for animations in WPF

I'm looking for a tool to create animations in WPF. The only tool that I know is Blend. Blend is for my purposes to heavy and I don't have a license. There开发者_JAVA百科fore I'm looking for a free tool - like XAMLPad - to create animations. Does anyone know some tools?

Thanks in advance!
