Vegreville egg
The Vegreville egg is a giant sculpture of a pysanka, a Ukrainian-style Easter egg. The work by Paul Maxum Sembaliuk is built of an intricate set of two-dimensional anodized aluminum tiles in the shape of congruent equilateral triangles and star-shaped hexagons, fashioned over an aluminum framework. The egg is long and three and a half stories high, weighing in at . It is the second largest pysanka in the world. The biggest one was built in Kolomyia, Ukraine in 2000.
Pysanka
Many superstitions were attached to pysanky. Pysanky were thought to protect households from evil spirits, catastrophe, lightning and fires. Pysanky with spiral motifs were the most powerful, as the demons and other unholy creatures would be trapped within the spirals forever. A blessed pysanka could be used to find demons hidden in the dark corners of your house.
Pysanky held powerful magic, and had to be disposed of properly, lest a witch get a hold of one. She could use the shell to gather dew, and use the gathered dew to dry up a cow's milk. The witch could also use bits of the eggshell to poke people and sicken them. The eggshell had to be ground up very finely (and fed to chickens to make them good egg layers) or broken into pieces and tossed into a running stream.
