Watch Me Go!

Using the same lenticular technology as the duo's Watch Me Hop!, this compact book creates the illusion of moving vehicles, including a race car, spaceship and fire engine. The movements, undeniably smooth and detailed, are “activated” when readers tilt the book vertically. Some are exceptional (an approaching train slowly floods a dark tunnel with light), as the eight machines identify themselves in bold, block print: “I'm a digger./ My treads go around./ Watch me go move the ground!” It's a simple, modest optical effect, but paired with the book's crisp silhouette backgrounds, it should hold readers' attention. Ages 3–up. (Sept.)
