Art that can fit into the palm of your hand

I really like this pocket-sized mural by street artist D*Face—his new collaboration with Zippo. From a Wonderland Magazine interview with the artist:

I'm typically not a very "mood-board" kind of person but it certainly made for an interesting challenge to create an artwork that fit both the wall and the lighter simultaneously. The stripes graphic worked nicely because you’ll notice the top stripe of the head pops off when you flick the top of the lighter – I liked the idea of the head and the flame being a kind of hidden alternate top piece to the design – setting my head alight or the ’spark’ inside my head… every time you use it seemed amusing too.
