Light barriers are surfaces that completely alter the area. We can use light barriers, among other things, to create artificial lakes or tunnels. It is an unforgettable experience entering into an event through a laser-created tunnel. It can be just as magical to watch ballet dancers perform one of your favourite ballet scenes on a lake made of pure laser light. How much artists and their audience are excited by lasers can be seen at Iva Pasarić’s ambient installation W. Her artwork has affirmed Prolight’s work in contemporary Croatian art.
