The Lunecase ($40) is an intelligent case that’s powered by electromagnetic energy and wirelessly provides you with visual notifications of incoming texts and calls. All electronic devices emit electromagnetic energy. The Lunecase uses this unused energy to transform the back of your phone into a notification center. Before the text or call even hits your phone’s screen the Lunecase knows it’s coming. All of this without the need for batteries or wires. It just makes you wonder what other potential uses are available for this unused energy. You can check out their Kickstarter campaign, which is still going on.
