Forget what you think you know about seeing 3D optical illusions. Forget everything you’ve been taught. This image is different, and if you want to unlock it, you’re going to have to throw your training out the window. Adopt a diet of foraged nuts and grains, and limit your liquids to distilled water and white teas. Sell your worldly belongings and buy a simple grass mat. Stare at the image before you lie down to sleep. Do this for nine years. In the winter of your ninth year, you will make out the dolphin.
