Didn't see this one coming: Apparently SketchBook Pro, the drawing app many of us designers know and love, is also a favorite app of Oprah Winfrey's. Hence O, The Oprah Magazine and Autodesk have teamed up to release Sketchbook O.

The spin-off app is freely available until March and is launching in conjunction with the "Creativity Challenge" featured in O's February issue. Filmmaker Miranda July has provided five "assignments" that O readers can choose to illustrate in the app (i.e. "Designate a place for something that needs a place," "Reenact something you do every day in reverse") and users can send their illustrations into the O website, with the best to be included in an online gallery.

Of course, that's not the best part, there's more. Ready? ...LOOK UNDER YOUR CHAIR!

I know, there's actually nothing under your chair. Sorry, got carried away.
