It is not available to the general public, but is kept in the secure vault room of the Pinacoteca Ambrosiana (a few yards from Milan cathedral). Using the technique of high resolution digitalization, the 100 most fascinating manuscript pages have been reproduced and collected into an interactive book, allowing the pages to be turned and examined directly – something never before available to the public. As well as the ability to zoom in on details with a totally new clarity of enlargement, the three-dimensional animations of the main drawings make it possible for the viewer to easily see how the mechanisms work.

The interactive stations in the exhibition allow access to the virtual Codex Atlanticus through plasma screens and video projections. Another exciting display in the exhibition is the physical reconstruction in wood and iron of the Multi-cannon Gunship, which is the drawing that appears on the very first page of the Codex Atlanticus. Naturally, this machine can also be viewed more closely at dedicated interactive stations.
