Crop Circle Armada

Saucer shapes move across the sapphire sky,
Their platinum hulls reflect rainbows of light,
A mother ship directs them as they fly,
Below them citizens tremble in fright,
Saucers hover above fields of ripe rye,
Direct their rainbows at the grain heads bright,
Grain stems flatten without any breaks,
The flattened stems form geometric shapes.
