Geometric Tunnel Pinwheel Logo

A dynamic green emblem featuring four interlocking, rounded geometric shapes in a pinwheel formation. The design creates a central diamond void, resembling the structured perspective of a tunnel entryway. Its rotating symmetry symbolizes continuous movement, efficient flow, and organizational synergy. The dark green tones against a lime-yellow background project energy, growth, and sustainable innovation. Ideal for infrastructure engineering, renewable energy firms, or modern logistics and transport agencies.
