Art is not what you see, but is what you interact with. Good paintings make their viewers imaginative. As every artist has been expressing love in many ways, the authors introduce a novel way to express the shape of love in an interactive way using state-of-the-art computing technology. The viewers of the art will not see the picture, but will interact with the picture literally. The concept of the interactive art that the authors propose in this paper is that the viewer of the art feel as if he/she is inside the painting. You first find yourself moving in the acrylic painting as if it reflects you like a mirror. In the picture you interact with a family of Alpaca, who will present you with a gift. If you stare at yourself in the picture carefully you will see your face is slightly morphed to that of your child age. You are to bring a candle with you to lighten the picture. As you move the candle, the lighting in the picture changes. You can even blow out the candle, and every animated character disappear from the picture, though the gift from Alpaca family remains inside you."
