Craft a scene within a medieval castle's great hall, where knights gather around a massive round table, discussing matters of chivalry and honor.

The vibrant dance of northern lights (aurora borealis) illuminating the starry sky.

A macro shot of a vibrant peacock feather with all its iridescent colors.

A vibrant supernova explosion in the far reaches of space.

An abstract pattern of swirling colors, resembling an oil slick or soap bubble.
