Keep It Cartesian has designed an outbox that conveniently attaches to the wall using a light switch.
Inbox. Outbox. Before e-mail there was mail mail. It’s actually still around. Light switches have stuck around for some time as well. The letter holder just showed up, but we like to think it’ll be around for a while too - just like letters and light switches. But if the post office decided to shut down, the letter holder is 100% recyclable. Or you could hold other things with it. Last time we checked, creativity is still around too. (via)
