Here's my submission for the mentos contest, I wanted to give the message of making the impossible possible. Used a double message here, the term "when pigs fly" and the sheer fact that he's using a bunch of pop bottles and mentos to enable him to do so.
As for making the world a better place, gotta acknowledge that the best ideas are often the craziest.
Wow I had to rush this piece, didn't know if I would get it done on time.
Edit: Funny enough I thought the contest ended 11 1/2 hours ago, major brain fart. I edited the image to fit the borders on the template, unfortunately that means I had to crop a tiny tiny bit more. I don't want to edit the template, I believe that is against the rules. This worked out also because I eliminated the tangent with the mentos hand going into the hogs arm.
