We love Sandify and it's been a great tool to experiment and see how tracks are made. Here are a few tracks we've created and like. It's great the .thr file has all the parameters in it at the head of the file so you can try it and make your own variations using these as a starting point.
Here are the .thr files and pictures of the results: http://tinyurl.com/sandify-pawliger
