In reality, the 3D object is based on a flat drawing of stairs supported by angled-polygon legs. The perceptual result is an ascending staircase from a given perspective and a descending staircase from a different perspective.

One user replied to the video on Twitter with 'he should've named it stairway to heaven' as a reference to the Led Zeppelin song, and we totally agree. Our minds might've been bamboozled, but we look forward to seeing what Merwe might come up with next. In the meantime, why not have a go at making your own illusions with this step-by-step guide on how to create 3D optical illusions.
