the panel named after the siberian tunguska was inspired by the largest impact event on earth. its convex spherical shapes emerge from the stately surface symbolizing the way the explosion left its devastating mark on a vast range of land at the beginning of the 20th century. as these shapes overlap, the intertwining circles also form curving rhombuses which mysteriously grow over the circles just like the orb arrived into the atmosphere and turned into a fireball – unexpectedly, but heavily with meaning.
