Who! It is a giant dream caller who has been a year since it was set up in the natural environment of the Altamira Museum in mid-May 2018. It is a participative installation, which invites the visitor to get in it and discover who has made the first art, the beginning of culture and of all humanity.

There is a participatory experience with the visitor, where he/she portrays himself/ herself in a mirror, the same that is part of the installation.
