Animated Flat Design Column Icon With Expanding Fill

This animated icon features a clean, two-dimensional line art representation of an architectural column. Within the simple black outline, two vibrant blue-green vertical lines expand and contract rhythmically, creating a dynamic filling animation. The minimalist, flat design aesthetic makes this graphic versatile for a wide range of modern digital projects. It is perfect for enhancing presentations, explainer videos, or corporate content that requires a symbolic visual for themes such as stability, foundation, or design principles. The subtle motion adds a touch of professional polish without distracting from the main message.
