Cubicle-trapped Cézannes and multitasking Matisses, prepare to bookmark: We've got your next big time-suck right here.

Sketch, the brainchild of Bay Area graphic design outfit Odopod, is one of the coolest, prettiest online drawing applications we've seen in a while. Faced with the blank page, choose brushes in various colors and textures to tackle your oeuvre, and follow your muse with the mouse: the results uncannily approximate the look of watercolor and ink drawings.

Clicking the arrows at the top of the screen takes you through works saved by other users, recreating the entire sketch at high speed before your eyes.
