The basis of the drawing is the shape of a butterfly on a background of an abacus (first tool used for counting which emphasizes the combination of time). The body of the butterfly has the shape of a person who has two wings, but actually it is an hourglass that measures time.
The wings are two clocks connected by a conveyor belt (looks like a chain). Through the chain connecting the clocks, two clocks are created that rotate in different directions (the rotation is indicated by the arrows). The whole image together forms the infinity sign. Time is infinite because it never stops.
