4 elements have been organically grown for 20 years with the public space of Banská Štiavnica. The celebration of this connection was also an interactive installation that allowed visitors of 4 elements and random passers-by to combine elements from the graphical identities of each vintage of 4 elements and to create their own temporary light installation directly in the public space in the center of Banská Štiavnica.

Interactive installation – Element digital graffiti – Intermediate artists Pavol Soukal and Lukáš Matejka from the civic association TRAKT have decided to realize on the basis of the need to bring current trends of contemporary art among the general public. Designer sprays, produced by 3D printing, have a small LED indicator instead of the dye. They are watched by an unobtrusive camera system that allows you to interact to produce accurate color image light. It is projected on the facade of the building. The viewer himself becomes an artist – a creative creator who draws, paint, spray on buildings. Graffiti inherently belongs to the color of the urban environment, whether in positive or negative form. In the case of Digital Digital Graffiti, there will be a small celebration of the 20th anniversary of the festival, as well as an invitation to the 4th Festival of Light and Shadow, organized by TRAKT in Banská Bystrica on September 21 and 22, 2018.
