Bold geometric pattern features four black squares with white space between them. The two diagonally opposed thick squares each contain a thin black circle with a thick equal sign inside. In contrast, the two thin squares each contain a thick black circle that touches the square’s edges with a thin vertical equal sign inside. The white is transparent, so you can change it if you like.
