Currently, there is only two simple list based effects. They aren’t perfect and I’m sure they could use some refactoring (currently doing this). See this blog post for more information and to submit any feedback/bug reports/etc. EffectsPack requires Prototype – Sam Stephenson and Effects V2 – Thomas Fuchs. The real credit goes to those guys who did all the real work.
