L'Ultima Cena Interattiva è un work in progress (basato su uno studio dell'applicazione del teorema albertiano della Costruzione Legittima compiuto nell'81/82 da Daniele Marini e Lorenzo Forges Davanzati) il cui obiettivo è realizzare un viaggio in realtà virtuale nel capolavoro di Leonardo. Il progetto, presentato in Italia e in Francia, in fase di realizzazione, vuole indagare le relazioni tra l'architettura reale e quella dipinta e oltre che in realtà virtuale sarà tradotto su CD-ROM e su Internet.

This installation is a Virtual Reality interactive journey into the Leonardo da Vinci's masterpiece: "L'Ultima Cena". The visitor can: ... navigate inside and around the church of "Santa Maria delle Grazie"..

... enter into the "Refettorio", navigate inside it and visit the Ultima Cena in its particulars...

... h/she can penetrate the painting and a 3D-recostruction of the Last Supper appears in front of the visitor. H/she can go inside the "room" where the LastSupper is taking place...
