Optical Illusions, by DK Publishing
Did she spend a lot of time examining “the dress” when the world couldn’t decide if it was blue and black or white and gold? Or, maybe she surveyed the whole family to find out who saw “the legs” as ultra-shiny and oily and who saw them as paint-flecked? If so, this book is an absolute must this year. Packed with pop-ups, eyeball-benders, tabs, flaps, and spinning disks, it’s analog entertainment to rival the Xbox. Not totally sold yet? There’s even a 3D sculpture that follows you around the room. The book also serves a science lesson of sorts, offering explanations for how the illusions work.
