I don't know if any of you have custom card printing machines, but Pims1978 over on Deviant Art has released a full set for any of you that want to ponify your next poker night.
Overall it hits 80 separate cards. It's a shame we can't get these officially mass produced by Hasbro or something! Though now that I think about it, the last time I used playing cards outside of Magic the Gathering was when I was in middle school. Confound this modern entertainment draining all my time!
