ESheep.exe is there a Mac version?

Hi you all...

does anybody remember the ESheep? The little sheep that hangs of your desktop windows, gets beamed up by aliens, hangs out with his little friend? It's a desktop toy which I can't find anywhere to run on Apple. It's an .exe file. I saw the listings, but sorry, too technical...

Is there a Mac version of the ESheep?

Please help..

Thanks so much
