So the animation was from forever ago. Atleast before 2008.
It was an animation with wonderful guitar song over the video. It was only acoustic guitar, nothing else. Because it was so long ago I vaguely remember what the actual video was about, but I distinctly remember a dancing cactus. The rest of the video was just creative trinkets and doodads of stuff interacting with eachother like a Rude Goldberg machine.
Please help!
EDIT: This was an animation on Newgrounds, not just a random video.
