Perpetual Motion Machine

The Perpetual Motion Machine is seen in the Royal Museum in Ultima VI. It is a machine consisting of several wheels and poles, that keeps itself in constant motion with its own motion, meaning that it never loses any energy. It didn't appear in later Ultima games.

In reality, such a machine is impossible, as it violates fundamental laws of energy and thermodynamics. Thus, the Perpetual Motion Machine was just a joke by Origin.
