Hushme Colleagues yapping on the phone nonstop while you're trying to work? Perhaps this totally-not-cosplaying-as-Bane mask -- aka the Hushme -- could help! Billed as the "world's first voice mask for mobile phones," it's designed to let a person gab without disturbing those nearby. It's also got a built-in voice changer, if you want to sound a bit more like Darth Vader. Yes this is a serious idea.
