“DOOM is a classic game to implement on a variety of platforms, but doompdf by [ading2210] is one we didn’t see coming. It runs a bit slow and controls are a little awkward but it does run. Entirely within a PDF file, at that.”

So, soon we’ll see Bad Apple in PDF too. If it isn’t already out there.

  Apparently it’s 6,500 files.
  
  Also not the only one.

    Heh, that’s one way to do it I guess. It would be more impressive with this doompdf format though, especially with ASCII.

As cool as this is, to me this just screams security issues. If scripting in PDF can run doom, it can be (and is) used for nefarious purposes. Wasn’t eg. LTT’s channel compromized because of a PDF with some nasty stuff in it?

  Just because you can render a game using scripting doesn’t mean your script can escape the PDF reader.
  
  You can build a fully working Turing machine inside PowerPoint, but without an exploit you are still not going to run code outside the PowerPoint environment

There’s also tetris. Wonder how they achieve randomness…
