Are you a maker who loves to travel?  Or a traveler who loves to make?  If so, I have a great new challenge for you―can you condense your travel memories into a mere six cubic inches? 
The idea is to reflect upon your travel experience and identify the few most significant qualities, tangible and intangible, of the place you visited.  And then to capture those qualities, as concisely as possible, in a pocket-sized box.  
The result is a tiny, three-dimensional work of art which I’ve dubbed the Travel Memories Mini Tin.
