Imagine that you live in the rainforests of Southeast Asia, you're a pint-sized primate with enormous eyes and you look a little like Gizmo from the movie, 'Gremlins.' You're a tarsier — a nocturnal animal whose giant eyes provide you with exceptional visual sensitivity, enabling a predatory advantage. A new virtual reality (VR) software, Tarsier Goggles, simulates a tarsier's vision and illustrates the adaptive advantage of this animal's oversized eyes.
