If you are one of those people that are incapable of turning off your cell phone, and don't always want to answer it either, here is a polite alternative. The Black Hole phone bag has a special pocket that blocks signal reception so you can't receive any calls. It also has another pocket that allows reception. It beats running into a closet, putting your fingers into your ears and shouting â€œMake it stop, Make it stop!â€
Implications - This little device really allows people to keep their phone on their person, but disconnect from the heavily integrated world of phone life.
It'll be nice to have a lot more friends be "present" in their conversations. The Black Hole is available now.
