Vinegar etched emu eggs mixed with plain emu eggs make an interesting arrangement in a shallow wooden bowl.  Another choice would be to use a skillet instead of a shallow bowl.  This would be an excellent use for a "cracked" skillet that would be unsuitable for cooking or unsightly on the wall.  If you use a cast iron container, consider using a cloth to cushion the eggs from the sides of the container.  Cast iron is slightly abrasive and may rub against the sides of the egg over a period of time, destroying any finish or artwork.
