It's a beautiful idea to use cloth on a large scale in order to have people experience space, light and color around them. Carlito Carvalhosa's Installation is an impressive example of this, though the element of recorded music might dampen the individual effect of walking the spiral, but so too would the sound of many people. It's interesting to think of the other senses as well, and how people would enjoy a piece in the best way possible. How would you engage more senses? What about taking into consideration Steiner's 12 senses?
