This advertisement is advertising the electromagnetic radiation in wavelengths of around 0.1 to 15 kHz that naturally occurs in the atmosphere. With the help of Stephen P. McGreevy's huge recordings archive and using ordinary drywall and simple space illusion we can see this untraditional field of human interest and fascinating natural phenomena. (Anifilm)
