One of my favourite comics to date:

Title Text: Some engineer out there has solved P=NP and it’s locked up in an electric eggbeater calibration routine. For every 0x5f375a86 we learn about, there are thousands we never see.
Its from XKCD.com. In these comics, the alternate text (aka title text… the text you see when you mouse-over the image) is just as important as the comic. I was curious why the author chose 0x5f375a86 so I googled it. Turns out its from this paper and shows how somebody coding for Quake came up with an incredible algorithm that sped things up by a factor of 4 without sacrificing the degree of accuracy needed.
Love it.
