Festival of light SIGNAL took place for the third time in Prague this weekend. It brought 3 large format videomappings (one of which was 3D), 13 light and 5 interactive installations. The organisers didn’t measure the turnout this year, but focused more on the cooperation with security services and on the improvement of passability of the streets. For the first time this year, SIGNAL expanded into the professional sphere with programs such as SIGNAL Future Forum or educational platform Transmit (www.transmit.org). Many works received great feedback from the guests, such as the videomapping on the church of St. Ludmila, the colourfully lit up Střelecký island or the interactive installation called Faces on the Šítkovská tower. SIGNAL 2016 will take place from October 13th till October 16th 2016.
