"A webcomic of romance, sarcasm, math, and language"
One-dimensional people with multidimensional minds
Possibly the geekiest (http://xkcd.com/c244.html) webcomic in wide circulation. It has interesting ideas about spam prevention (http://xkcd.com/c233.html), among other things.
I have a hard time reading this comic. Each time I want to scream like the bene gesserit witch "get out of my mind!!!". Seriously though, I envision this comic with little strips all over IT shops and CS buildings in the near future. Also, the one I keep up by my computer is this: http://xkcd.com/292/ -- LayneThomas

As a math teacher, I particularly enjoy this one: http://xkcd.com/135/ -- PaulMiller
the ultimate XkCd ever:

I use that in one of my university database lectures. -- DaveVoorhis

Another fan art: "Readers Digest" published a cartooney version of the Spirit & Endeavor missions...
...with a slightly more emotional robot going "I think I can I think I can" as it chugged up a rise.
