The internet and the age of social media seem to be opening up doors to reinvent the medium and reignite those in-theater experiences that have gotten stale over the decades. The following video features an explanation of the intent behind the Kickstarter campaign:. Fact Checks. A video documents the existence of a never-ending "Escherian Stairwell.
There is one stairway leading down, and another leading up. You walk up to the top of the stairs, then go down two flights, and walk around the corner. You then go back and edit the tape to look like you just came out at the bottom. For the part where you walk all the way around with a group of people holding hands you have to have at least one set of identical twins.
In the famous escherian stairwell video, they have those black guys. You get people to connect hands. Then you show the first twin, without showing who he is holding hands with.
Then you walk around until you come to his twin brother. Make sure you don't show who he is holding hands with, because you can only repeat one person, unless you have more than one set of twins.
That is how the escherian stairwell works. Pretty clever huh? Its actually just takes some simple video editing to make it work. Also, it helps to make up a fake tv show and call it episode 3 to lend it credibility. The secret of the Escher stairwell is that it is an illusion. You mean the drawing by Escher?
