This installation is a mechanism that serves as a kind of interface between planetary processes and an audience. It consists of 12 transparent piezocrystals, grown especially for the project, and 12 motorized hammers that strike them. The installation is connected to the internet. Its core algorithm is controlled by data from a meteorological site which shows lightning strikes in real time (on average, 10~200 lightning flashes occur on the planet every minute). Each time the installation receives information about a lightning strike, a hammer strikes one of the crystals, resulting in a small electrical discharge produced by the crystal under mechanical stress. Each of these charges activates a powerful lamp and sound effects.
