The good folks at Doodlers Anonymous noticed a trend (perhaps amongst themselves) of people defacing, drawing and scrawling thoughts across the now iconic red frame of the Netflix envelope.

They shared some submissions at their site and received so much love for it that they created a blog devoted to the doodling subculture: Doodle Flix.

Maybe the urge to doodle happens because of the envelope's wide-open real estate, maybe it's a gesture to amuse the mail man or perhaps it's an attempt to communicate with the mysterious envelope stuffers at Netflix HQ, whatever the motivation, the results are entertaining. See some of the doodles below.
