Bing Maps "Destination Maps" Map App lets you create custom mini-maps that you can save, print, or share via URL.
"These maps can either help people who don't know your location very well or just be a fun addition to a party invitation. And if you're not having a party anytime soon, check it out anyways! You can choose from 4 different map styles, including the Treasure Map style as seen in the below example."
Please note that the app takes between 2 and 4 minutes to generate the map.
