It's supposed to snag a picture off your desktop to freak me out. Mine was a meme and I laughed.
You are the computer itself. Nothing around you is real, it’s all a digital manifestation of the data in the computer. That’s what the ending tells you. You’re sitting at a “desktop” with games, and pictures on it, and there’s a trash bin nearby. You are the main character (hence why it calls you by your name).
