Why are butterflies so beautiful?

How does evolution explain the glorious patterning? Is there something in DNA that knows exactly how to place a line? It's not just butterflies, many plants and animals have lines and colours that seem designed for "aesthetic" effect. How on earth can that be encoded? - there simply isn't enough coding potential in the DNA system we're supposed to credit for it. How on earth, I repeat, can a plate full of amino acids resolve themselves not just into little robots, but into aesthetically drawn lines and colours, as well as living, wriggling, flitting, galloping creatures that put any imaginable battery power and programming completely nowhere by comparison. You can take any combination of chemicals you like and place them on any planet you like for however many million years, and you can pretty well guarantee that if you could come back in a billion years they'd still be sitting where you left them. They just don't do anything.
