An alternative to walls

Soo currently we have been given a new project for this semester and the brief wasto design an urban hub for a company Called SEPA. The ideas i have came up with are Earth, fire, water and wind, the natural four elements of the world

I found a quote here

'' The four elements are the building bricks of the universe. many believe that they are also part of basic structures themselves'

In my design i shall relate everything  to these natural elements including materials.
Soo i was thinking what can i relate to air and came across this interesting sculpture called a Hypoosurface wall. Hyposurface has come up with a wall that can react to sound and movement as well as spell out words, make pictures etc

not sure if it is very sustainable, but pretty cool none the less.
