Doom Runs in a PDF: A Testament to Programming Ingenuity

Programmers have ported the classic game Doom into a PDF file! This isn't a simple embedding; it leverages PDF's Javascript capabilities to render Doom using clever ASCII character manipulation within a PDF reader. While the frame rate isn't high, it's playable enough to deliver a nostalgic experience. This feat showcases the latent potential of the PDF format and serves as a reminder that seemingly static PDF files may hold hidden surprises.
