All the cool animation curves from `CAMediaTimingFunction` but not limited to use with CoreAnimation. See what you can do with cubic Bezier curves here: http://netcetera.org/camtf-playground.html To get started just "Download Gist", throw the .h and .m files into your Xcode project and you're good to go!
