Rubikon is a cut-out that will become a functional camera (camera obscura) after gluing.
 The Rubikon cut-out was first published in 2005 in the 8th issue of ABC magazine, 25 years after the launch of Dirkon. Since then, it has also been published in foreign photography media. Rubikon is also used as a teaching aid at some secondary and primary schools, or has become a supplement to several exhibitions dedicated to photography.
