My current pfp is a simple photoshop of the boc pioneer plaque, with the man's head swapped with the hexagon. I just did that for a laugh on this site.
But my avatar before this, and the one that I mainly everywhere else, is a picture of me that's been run through several AI programs until it became an uncanny, exaggerated approximation of my face.
I also have several variations and iterations of it, sent through even more AI.
Like this one (sorry for the small size), where I gave it horrific smile
This was done by continually sending it through an AI that makes people's smiles larger (the very same AI that's responsible for the jermaSUS face), and then taking each image and using another AI tool to string them together into an animation. No clue why he gets more green though...
I have so many more though: one where I made him a kid, one he's an old man, another he's merged with the faces of other people, etc. etc. etc...
