78% is collaborative multimedia exhibition between Živko Toplak and Eklego, platform of visual dialogue (Matija Raos & Ivo Toplak). We were called by the artist to co-create visual and emotional experience promoting the importance of the water. Artist Živko usually creates with the water (and color) but this time we proposed the idea to create without the use of any water as a willing sacrifice bu substituting it with the light. Artist created pieces using Blinddruck technique and we designed special computer controlled LED light program (LED) that we used as art piece developing tool creating strong but intimate visual story followed by important ecological message. All visitors before they entered the exhibition were also given the earplugs so whole experience was pushed even further by creating total submerging effect.
