Definition

eu·sta·sy /ˈyo͞ostəsē/
Noun: A change of sea level throughout the world, caused typically by movements of parts of the earth’s crust or melting of glaciers.

The term applies to how we aspire to spread a change around the world, & is the source of our color scheme (navy blue, & 30% grey with just a hint of blue). It also inspires some of our more famous metaphors, relating to business, advertising, & security, which are replaced with references to the seas & oceans.
