I've posted some pieces in odd scales on this site, Here they are in order of difficulty:

When I've updated it it will be nearer 60. Go to "Friends", then "Andrew F." and then it'll be easy to find.

Lots of these are freaky, my favourites are Harmonic Minor, Bhairava, Reverse Harmonic Minor (more usually called Harmonic Major) and if you want something really frightening try Hungarian major or Enigmatic.
If I couldn't laugh at myself how could I laugh at someone less ridiculous?
