In the Eastern Orthodox and Greek-Catholic Churches, the Paten is called a diskos and is elevated by a stand (or "foot") permanently attached underneath. The diskos is usually more ornate than its Latin-Rite counterpart, and must always be made of gold or at least be gold-plated. The diskos may be engraved with an icon of Jesus Christ, the Nativity of Christ, a cross, or more frequently, an icon of the Theotokos.
When a diskos is made, it is usually accompanied by a matching asterisk (small, folding metal stand used to keep the Aër from disturbing the particles on the diskos), a spoon (for distributing Holy Communion to the faithful), and a spear (used to cut the Lamb during the Liturgy of Preparation).
For Christians of the East the diskos symbolises the Virgin Mary, who received Christ into her womb, and gave him birth; and also the Tomb of Christ which received his body after the Crucifixion, and from which he resurrected.To the other:
you can also scroll down for pre-cubed Communion bread (which according to the URLs is unleavened?)
"Product has a 6-month shelf-life and boxes are stamped with expiration dates." [After they expire, do the Elements resurrect? After Jesus goes bad, does He turn into Cassandra Nova?]
[So says Keith, anyway. I declined to suggest that not having Communion would be the farthest low end of liturgical spectrum -- mostly because I didn't think of it until after the moment had passed.]
