Our students from the blended learning programme met up for their summer seminar in Bangkok. One part of this workshop was a lighting mock-up at the UNESCO world heritage site Wat Mahathat in Auytthaya. The students prepared a lighting design concept to develop a lighting design master plan for this area afterwards. Before starting this project Prof. Dr. Acharawan Chutarat, from KMUTT University, held an introduction seminar about the temple area and the historical background.
