Writing a love letter to a geek girl - Google Map Envelope

Here are two designers Rahul and Yofred.

What is it like if Google map becomes an envelope, they imagined.

There would be a Send envelope button in Gmail. It'd be great to allow people mail physical letters trough the postal service for a small fee with this button. But their creative mind didn't end here.
When press the button, users were also able to print out templates which show the route from an address of a sender to an address of a recipient on Google map.

The printed templates can be folded to make envelopes. You put your letter in the envelope and post the mail.

If you are in long-distance relationship, the envelope tells a story itself. If you recently moved and want to tell people the new address, this is a convenient way.

If a girl you want so badly is a geek, this is how you can make a nice love-letter.
