Brewmeister Jeff was working on a Spotted Cow clone, but he hasn't said much lately about it. You could always try searching for spotted cow, and look at any posts from him- that might help you.
I sort of came up with a Fat Squirrel clone, and Bernie Brewer has brewed it a couple of times, I think. I'm sure it's still posted here on HBT.
