HB-Laser installed a massive setup of multi media show and laser show at the Tenglong Cave in China. This 52km long cave was said to be the biggest tourist attraction in China. The multi media laser show is split to several areas of the cave. Several major challenges made this project very difficult: Not only was the electrical infrastructure insufficient first, there was also a rather high humidity in the cave and the low temperature didn't make things easier. So many adaptions and preparations were necessary to make this multi media project happen.

This show production was a time code controlled turnkey solution with complete installation including video production and show production according to the chinese story-board.
