Ortoceres is a stage in the Fishing On Orfű festivál - as know as PMFC stage. The basic idea was to create a big cone, what includes place for the musicians, and the audience as well! The main structure - what is our own design - are series of 15 degree offset hexagon sections which are expanding and expanding!
Originally Orthoceras referred to all nautiloids with a straight-shell, called an "orthocone". But later research on their internal structures, such as the siphuncle, cameral deposits, and others, showed that these actually belong to a number of groups, even different orders.
