Did you ever see one of those auto-generated random “academic papers” like this one? When I first saw the following title, my first thought was that it is a randomly-generated “paper”:
Implications of the Turing completeness of reaction-diffusion models, informed by GPGPU simulations on an XBox 360: Cardiac arrhythmias, re-entry and the Halting problem [PDF]
Turing completeness, [...]

Not many developers have the insights of Michael Abrash. He is a game developer with decades of experience building commercial games, including a game you may recognize as "Quake". His Graphics Programming Black Book is years old, but much of it is just as interesting as it was at the time of writing. And, the [...]

For example, the Back and Forward browser buttons do not always work as the user may expect with Silverlight apps. The set of browser features [...]

It took significantly longer than I expected, but the RoboZZle demo video is finally on YouTube.
The video made the reddit front page, so you can read the usual mixture of insightful, funny, and outright insane comments on the reddit page and the YouTube page.
My favorite funny comment is this one:
And finally, this is the video:
