Meet Beatriz:

"He said...he said that my smile stretches across my face like a butterfly...Then he said something about my laugh. He said my laugh was a rose, crashing water. He said my laugh was a sudden silvery wave."

"There was once a poet named Dante who fell in love with a woman named Beatriz. It seems that Beatrizes provoke incommensurable loves."

(---from The Postman by Antonio Skármeta)

Online, there is only the Bea-Bot, of course, but you can write her a metaphor and she will respond in kind.
