"Still life" is a common subject for artists. In a "still life", the artist shows us something living, but not moving. Typically that's fruit in a bowl, or a sleeping cat, or flowers in a vase.
In this picture, we have all that... but there's a terrific sense of motion. A pencil rockets from left to right. Scissors cut paper. Dark water ripples. An alarm clock rings. A pencil rattles in a coffee cup.
Once again, Escher style art makes fun of the audience's assumptions. This time, the audience assumes that a still life is... still. Count how many things are motionless. How many of those are "life"? How many things are in motion? How many of those are not alive?
What drawing techniques does the artist use to tell us things in the picture are moving? Which techniques have you tried?
Try to imagine this scene, 3 seconds after the moment it captures. What will have moved? Where will the pieces fall or speed away or tip or collapse? If you do this as a school assignment, have some students look at this picture upside down, others with the picture tipped 90 degrees to the right, and others with the picture tipped to the left. Have some students imagine the scene 2 seconds later, while others imagine the scene 30 seconds or a week later.
