Structure for H.O.R.S.E. tournament?...

[CptMisery]

Hi,

A group of us have been playing NL Hold'em tournaments for a few years now and are looking for something a little different so one guy said let's play a HORSE tournament. Well everyone thought it was a great idea, but nobody knows how it would be structured. Can anyone recommend a structure, or somewhere we could find a structure for this type of tournament?
