This dancing can animation was created in After Effects. I picked a fun song that would be amusing while watching a can "dance." I used a tool that pinches each side of the can and makes it move from the center. I added a background to make the animation more eye catching. 

This animation was created in flash. Everything is hand drawn. The first scene is a jeep driving. I made the wheels and the background move and kept the jeep still but made it look like its moving forward. Eventually the jeep ends up at the beach and then driving back home when the sun goes down. I used keyframes for everything that moves.
