You know how it really sucks when all you want to do is doodle on a cardboard box, but you A. don't have any cardboard boxes available and B. left your multicolored Sharpie pens at home?

Well! Thanks to the box doodle project, this horrific hypothetical never has to be your reality! Just head to the site, grab a virtual Sharpie and cardboard box, and doodle to your heart's content. (Click on the sample in the third column of the page to start, and turn off your pop-up blocker if nothing happens.) German artist David Hofmann's vision for the site: "Make the most out of least."

When you're done with your doodle, take a minute to browse the galleries -- there's plenty of amazing cardboard box art to see, like the cute little piggy at left, by Natalie Whitworth.
