“DNA. The great book of life from Mendel to genomics” is a major exhibition inaugurated on February 10, 2017 at the Palazzo delle Esposito in Rome. The event - curated by Telmo Pievani, Bernardino Fantini, Sergio Pimipinelli, and Fabrizio Rufo - aims to address in depth, but not technically, the various issues related to genetics and genomics and to provide, in particular to the younger public, the tools to understand the impact that discoveries in these fields will have on the society of the future. Limiteazero has designed and created all the multimedia installations and interactive exhibits in the exhibition. DNA - Matrix is an environmental projection that welcomes visitors at the beginning of the exhibition: it is characterized by a plastic and innovative representation of the double helix of DNA from which “cascades” of nitrogenous bases emanate that form figures that portray different living species. Mendel's table is an interactive exhibit that allows visitors to relive the famous experiments that allowed the monk of Brno to formulate the laws of inheritance. Face to face with Mendel is a multimedia intervention where some elegant environmental animations interact with objects that belonged to the father of genetics. The chromosome forest represents a physical and virtual exploration of the nucleus of a human cell: visitors, by selecting a certain chromosome on a console, can discover which genes are involved in the transmission of certain characters and how this happens. A large projection visualizes, using the video mapping technique, the representations of the selected chromosomes and the salient facts related to them. The experience is completed by a plastic representation in exhibition form of the entire human chromosomal system. Dolly and the others is an installation project that tells how research and experimentation on animal clones have evolved from the Dolly sheep to the present day. The installation looks like a large projection synchronized with a lighting system capable of highlighting the themes covered by underlining with light some sculptural elements (created by Lorenzo Posenti) that will thus represent the fundamental stages in the history of cloning. The jungle of the genome is an interactive exhibit that allows us to delve into the similarities and differences of some significant genomes - and explanatory of the complexity of the subject - through the languages of the infographic. Which of these foods is' natural '? It is an exhibit that makes us discover how many foods that we consider natural are actually, although this may seem counterintuitive, the result of selection or other genetic modifications. The intervention allows the choice of the topics covered through a “physical” interface; users, by placing plexiglass discs on a “hot spot”, can thus activate some animated infographics.
