Escherian Stairwell

An apparent stairwell located in RIT building seven. The Escherian Stairwell is seemingly never-ending as it loops continuously either up or down depending on which direction an individual goes.

RIT Student 1: "Hey do you know where my class is?"

RIT Student 2: "Yeah. Just go up the Escherian Stairwell until floor five."

RIT Student 1: "This is a three-storey building."

RIT Student 2: "No it's not. Wanna go to class or what?"
