We have used fantastic 50W green laser from Kvant company to illuminate space over the city Košice. Another two 8W green lasers and one 10W full color laser were used to draw effects on old mine building.
Since the distances of the lasers were too wide, it was not possible to use signal cables. That's why we have used new upcoming Fiesta.NET controller and wireless WiFi connection to control all 4 lasers in real-time from one computer!
Great light show was arranged by Dj Center company.
