The insignia seems to represent the same thing that the song I am the Walrus does. That is a a focus on the Book of Revelation and the coming Apocalypse.
Who are these people?
The House of Stuart is a European royal house. Founded by Robert II, the House of Stuart—also spelled Stewart in Scottish contexts—first became monarchs of the Kingdom of Scotland during the late 14th century before inheriting the kingdoms of England (including Wales) and Kingdom of Ireland in the 17th century. The dynasty's patrilineal Breton ancestors had held the office of High Steward of Scotland since the 12th century, after arriving by way of Norman England. In 1707, Queen Anne became the first monarch of the United Kingdom of Great Britain. The family also maintained the traditional English claims to the Kingdom of France.
In total, nine Stuart monarchs ruled Scotland from 1371 until 1603. James VI then inherited the realms of Elizabeth Tudor, becoming James I of England and of Ireland in the Union of the Crowns.
Symbols of the union
King James devised new coats of arms, a uniform coinage and the like. The creation of a national flag proved contentious, designs acceptable to one side typically offending the other. James finally proclaimed the new Union Flag on 12 April 1606: Scots who saw in it a St. George's Cross superimposed upon a St. Andrew's Saltire sought to create their own 'Scotch' design which saw the reverse superimposition take place. (This design was used in Scotland until 1707.) For years afterwards vessels of the two nations continued to fly their respective "flags", the royal proclamation notwithstanding. The Union Flag only entered into common use under Cromwell's Protectorate.

During the reign of the Stuarts, Scotland developed from a relatively poor and feudal country into a prosperous, modern and centralised state.[clarification needed] They ruled during a time in European history of transition from the Middle Ages, through the Renaissance, to the midpoint of the Early modern period. Monarchs such as James IV were known for sponsoring exponents of the Northern Renaissance such as the poet Robert Henryson, and others. After the Stuarts gained control of all of Great Britain, the arts and sciences continued to develop; many of William Shakespeare's best known plays were authored during the Jacobean era, while institutions such as the Royal Society and Royal Mail were established during the reign of Charles II.
