As noted above, this animated video entitled "Crater Face" will make you cry. It relies heavily on the "Bambi Eyes" phenomenon, which is pretty effective, in the sense that you are completely aware of being crudely manipulated, but yet your heart still goes "Whaaaagh" and you cry.
At first I thought the moral was going to be that humans are awesome and can fix anything, but then (spoiler alert) the astronaut DIES! So the craters can be together! I totally did not see that coming and was actually pretty moved and saddened by it.
Also, several scenes reminded me strongly of Ren and Stimpy creator John Kricfalusi's work. Any time a face or body is aggresively contorted and you see veins and stuff, I think of John. Did you know that he has a pretty cool blog? It's true.
