checkpointmedia has designed and produced a "volcano pump" for the refurbished Geology Room at the Museum of Natural History Vienna, which was opened in 2009.
The media station consists of a large flat screen standing on end and set into the wall, a PC, subwoofer and bass shaker. Initially, the screen shows a cross section of a volcano. Through the operation of a mechanical pump, the magma chamber fills with lava and as the pump meets greater resistance so the pressure increases inside the volcano. The climax is of course the eruption of the volcano that the visitor not only sees but also hears and feels by means of vibrations of the floor.
Lastly, an extreme pull back camera shot shows the visitor how the ash cloud blocks the sun's rays over a long period of time and affects the climate all over the world.
