TheParallaxView is an awesome optical illusion created for an iPhone X, implementing the phone’s 3D head tracking device to build an realistic depth view. An astonishing test by Peder Norrby!

Note that this is a monoscopic effect. When using the app IRL, the illusion is best seen with ONE EYE – the other eye closed. (Also works great for video since video is monoscopic). For a stereo effect some type of glasses would be needed (anaglyph or active) and the app adapted for it.
The app, called TheParallaxView, has been submitted to the app store. It has not yet been approved.
