In the Coptic Church we have a peculiar tradition. On Paschal Eve of Wednesday all the way to the end of Good Friday service, we are "not allowed" to greet one another, to remember not to greet one another in treason like Judas.
On Covenant Thursday, we do a "Judas procession", where we start from the nave of the Church, and walk backwards around the Church, with our cymbals backwards, and clockwise. I've heard other Coptic Churches do other interesting things like place a chair at the nave upside down. In this "defamatory procession", we chant a hymn that condemns the actions of Judas, calling him "breaker of the law".
It seems upon further discussion with some rites experts that this was a very late addition to the Coptic Church, post-14th Century, since manuscripts before that did not have this rite. But I was interested if other Orthodox churches, Eastern or Oriental, seemed to have anything in their tradition pertaining to Judas.
