The visual are seen in a baroque frame, Cudi explained on Twitter saying: "all my videos will be in a baroque frame. I create art, so it will be presented as such. ART IN MOTION"
In a 2013 interview with Complex, Cudi explained why he used certain imagery in the visuals for "Just What I Am":
"Yeah, it’s funny. People in my life know that I’m a fucking goofball. I’m a prankster and I clown a lot. In any moment in time, I’ll incorporate some jokes in my music or raps or whatever. And all throughout my career I’ve noticed that the main thing people try to point out is the Illuminati, Satanic symbols and references in music videos—specifically in my shit. And like, in no way shape or form am I the type of individual that will be ever thinking of that type of shit while we were working on these videos. But it’s so interesting to see how sure of themselves people are, talking about this. It’s like, 'No, I know it, I know it! He sold his soul to the devil! I know he’s friends with Satan! I can feel it.' You know what I mean? Niggas be knowing I guess. So my way of tricking everybody, being that I had that control, I was like, 'Oh man. Wouldn’t it be cool if we just threw a bunch of fucking Satanic devil-worship Illuminati symbols into the video, just like abruptly popping up all over the place and fuck people up?' Just to fuck with them and then not say anything, like wait months and not say shit. Just let ‘em trip out, just let ‘em talk. Ignore it if it comes up in conversation. It was an experiment, like we totally experimented with this. Right now as we speak, it’s still going on. Kids are so outraged."
