Eternal Research launched a Kickstarter for "Demon Box," stating that it is a "gateway to the unseen and unheard frequencies that surround us." It harnesses electromagnetic fields (EMF) to turn ordinary objects into musical devices. As long as the object emits electromagnetic waves, it can be used to create unique sounds. According to the Kickstarter page, some objects compatible with the Demon Box include mobile phones, wi-fi routers, microwave ovens, electric guitars, computers and laptops, neon signs, radios, televisions, power tools, and much more.
