Let yourself be drawn in by this pop-up card's colorful exterior, with a bright turquoise background and a brilliant hummingbird flitting over a patch of daisies. Similarly, vibrant hummingbirds dance across a collection of delicate daisies when the card opens, producing a 3D effect that brings the greeting card to life. The daisies and hummingbirds sit on a cool blue background, which makes it appear as if the birds are perching in the clouds.
