I saw this on the Jim Henson Company’s Facebook page.  For a Henson fan and/or aspiring doodler, this looks like a treat!  Set to be published October 1st, the interactive art book offers prompts like, “Doodle your inner glutton” and “What does your dream life look like?” (see the sample pages on Amazon).  It also includes examples of Henson’s own doodles.

By the way, I’m sure you’ve seen the Google tribute with the interactive Muppet doodle?  This is what one person did with it.  Classic 🙂
