The place where the world comes together in honesty and mirth. Windmills Tilted, Scared Cows Butchered, Lies Skewered on the Lance of Reality ... or something to that effect.

Finding The Ocean Inside An Opal
Opal is a hydrated amorphous form of silica. Because of its amorphous
character it is classed as a mineraloid, unlike the other crystalline
forms of silica which are classed as minerals.
The internal structure of precious opal makes it diffract light;
depending on the conditions in which it formed it can take on many
colors. Sometimes, when the light hits an opal, it looks like an underwater scene from the ocean.
