This post explores a set of elements which can be used to add function to space. This objects could also become isotropic and function as tables, storage units, sitting surfaces, sleeping, isolating spaces.
Different elements can be added to offer more tactile contact with the body, specifically hands.
Even gripping surfaces can have a huge variety, and add a huge tactile and functional diversity to space. Above you can see a study of grips used in bouldering.
Finally different tubes of different sizes can replace and offer different types of movement through space. The plate above explores how you can use tubes as a staircase, ramp, ladder.
