Old Western town at high noon, with dusty streets, saloons, horse-drawn carriages, and cowboys in a standoff.
A person's hands holding a piece of coal or charcoal, with brilliant sparks and flames emanating from it.
A narrow, rickety bridge crossing a fast-flowing mountain stream.
A futuristic Martian colony under a dome, with red rocky landscapes, advanced habitats, astronauts exploring, and Earth visible in the sky.
