Design an AI program to simulate the creation of a retro-style sign arrow mounted on a wall at a height of 2.10 meters. The program should include features for customizing the arrow's size, color, blinking pattern, and any accompanying effects to achieve a vintage aesthetic. Additionally, it should allow users to preview the arrow's placement on the wall and adjust its position as needed for optimal visibility and aesthetic appeal.
