Building virtual portals are popular practice for developers to demonstrate the "wow" factor of augmented reality.
Since the introduction of Apple ARKit, several demonstrations have shown how iPhones and iPad users will have access to their own alternate worlds when iOS 11 arrives this fall.
The latest such demo comes courtesy of independent developer Gian Piero Gigli, who posted a video showing off his portal to an oceanic environment.
Watch the full demo below. Gigli has also built demos of an augmented reality automobile manual and an animated zombie concept with ARKit.
