I’m no fan of monarchy, to say the least, but today’s invention is illustrated by the queen of england.
It’s a chess piece made using the figure/ground illusion.
More specifically, the idea is to create chess sets, each piece of which would be made from the profile of one of some set of famous people, rotated about their vertical axis.
It could be the royal family of your choice, the 1966 world cup side or one of the Game of Thrones dynasties.
This would help to make chess more accessible to people who find knights, rooks and bishops hard to identify with.
