Snail Mail Machine

I propose a machine for fueling the enduring nostalgia associated with paper envelopes. It will sit next to your computer, and every time you receive an email it will drop a real envelope through a small slot. Every envelope will have your name on it.

It's essential to keep the technology as invisible as possible. It should not be complicated by a printer that prints the name of the sender on the envelope, for example. The idea is that someone has just dropped off a letter by your computer for you to read.

When you remove the envelope from its holder (or, perhaps, place it back inside the machine) a window should pop up on your computer that shows you the email.
