The second library square has been made to produce a gentle more subtle feeling for people who are sensitive to their sense of touch or who has re- awakened their touch sensors. The texture has been based on natural rock textures because we belong in nature which naturally calms the mind. It will also provide enough sensory feedback, if you like it for a little feel-good hormone to be released, helping you cope better with your day. Similar to the feeling of buying something you like or receiving a text from a friend.
