Check out the Pocket Mod. Give it a whirl by clicking on the button on the top right. And on that page, check out the video.
I passed the link around to my coworkers, and Jane ended up printing out a version and cutting/folding it for me! I chuckled a good deal though, on seeing the address. 666 Happy Street? We were all joking that there would be a ton of laughing kids playing on Happy Street, but that the house at 666 would be in shambles, with a storm cloud hovering over the roof. LOL.
Thanks to Jeremy (aka wyndom earle) for the link.
