The link above will take you to my latest find in Digital Art, Narrative Movie Charts!
Even though the art wasn't created through digital means, the dude that created XKCD takes his hand-drawn comics and digitalizes them (AKA Scanner) and distributes through via digital methods. The site has a large collection of these very intelligent comics, all of which can be ordered in print or t-shirts. IF you're up for some procrastination with some intellectual stimulus, I invite you to click through the site. But let me forewarn you, it can get addicting.
The title "xkcd" was chosen because the word has no phonetic pronunciation. Why? Who knows, the creator used to work on robots for NASA.
