The interactive light installation, inspired by the iconic game Tetris©, combines the architectural heritage of the last century with modern technology. After scanning the QR code with their mobile phones, viewers can control the falling forms of light in real time, which are projected onto the glass-block wall of Vilnius “Vytis” Gymnasium. “Blocks” is a technology and art project that combines different forms of expression, transcends the boundaries of traditional play and becomes a new creative opportunity.
