The request of the project was to find a place and a way where people can demostrate when they want. If they want to demosntrate it´s because they to be seen by others and be listened by another people, so if this places were in the principal roads around Madrid would be better. Closing this roads and using a green area with a lot of mirrors and glasses, we would get the impression of more people than there would be; the reflection of the mirrors and the glasses, and the diferent types of interations turn into the "demosntrate place" to a special place to share opinions and to show our dissatisfaction with something.
