This has been designed specifically with Audio Mulch in mind, although when treated as an insert effect will work in other VST hosts. Percolator is based upon the obscure Boss PC2 Percussion Synthesiser. Feed it rhythms and it will reward you with a variety of fascinating percussive textures.

I have absolutely no idea, if this is a good plug or not but it sounds interesting and it's free, so why not try it?
