The 'Sensuous impulse' in design as a term, became popular in the Rococo period. It is a design idea that is pleasing to the eye with curves and flowing Rocaille shapes (which is a shell like design), instead of the straight line. Key aspects of these designs is the feminine side that is shown in the soft winding and twisting shapes, also with the shapes and sculptures that remind people of nature and freedom. This period also had designs that were classed to be very suductive and appealing to the viewer. Even though this design was very popular in the 18th century, a lot of contermporary designers still look back for inspiration and ideas for the future. The Pinchbeck box from a chatelaine is a classic example of a 'Sensuous Impulse' design from the Rococo era (1750). This design has the Louis XIV ear shell scrolls, but also has the asymmetrical use of motifs.
