Melvin holds the distinction of being the world’s smallest Rube Goldberg machine (although I have no idea who is keeping track of this kind of thing). I’m a sucker for this kind of whimsical engineering (I’ve featured Rube Goldbergs silly, historical and incredible before).
Melvin completes a simple task: He prepares postcards. But he does a little more, too. Traveling the world in two suitcases, he snaps a photo of anyone watching and posts it to his Facebook page. Just like a real traveler! Snapping pics, sharing with friends, and writing home.
