concept art piece for a large wall or gate, set in an indoor arcade. The design should echo the charm and playfulness found in Hearthstone's card frames and mana crystals, as well as the colorful and fantastical aesthetic of World of Warcraft. Integrate a touch of futuristic whimsy inspired by Rick and Morty's portals and universe. Use concentric hexagonal shapes, prominently displayed in a simplified and stylized manner. Envision the wall as a 3D-rendered concept, placed within an indoor arcade setting. The color palette includes dark orange, light orange, slate blue, and pink. 3d render, hexagons, minimalist, simple, concept art, arcade
