Create a joyful, minimalist human figure using the letters "L", "Z", and "Y". The letter "L" forms the body and legs, "Z" becomes dynamic arms in an energetic, waving motion, and "Y" forms the head or face, with the upper parts acting as raised arms in a joyful pose. The design should be simple, clean, and elegant, using only one color, with a modern and playful style that appeals to both children and teenagers.
