the sound which the user starts should be continuos, meaning it mustn’t be interrupted  when a they change a button.

The sounds the that represents city in the other paths  for the city to should be: people talking and then if the take a second step in to the grey the user should hear city scape.

(Type-thinking) so what happens when users go to green from blue?They should start with birds and bees, then get to more serious animals.

what about to blue from green a river that trespass, then (maybe) something that can generate bigger waves.

finale

and this to be experienced on Saturday the 22nd of May wuhuu! (yikes)

The theme
Being immersed in to the the externalities of the world in a very simplified, shirinked and reduced virtually real environment.
Instruments
A room / A projector / A flash based interactive website / 12 buttons attached to the As / for users to interact.
Approach suggestion #1:
Having colours (empowered with sound  efffects such as, city scaipe, animals, wave, heartbeat)as minimalistic representives huge space that is naturally or artificially builded around us (city, jungle, sea, body , desert). The sounds and the spaces will be represented by plain colours (grey, green, blue, red, cream).
As the user advance towards the room, by activating the buttons by their steps. Colours get darker and sounds get more intense (faster hard beat, a more crowded street in the city, more animals in the jungle and stronger waves).

Approach suggestion #2:
I also have fleeting ideas about having a game inteface for different set of profiles, but this is to be considered and structured with a better fashion.
