Picture of Impossible Staircase

The Penrose stairs, also known as the impossible staircase, is a two-dimensional depiction of a staircase in which the stairs make four 90-degree turns as they ascend or descend yet form a continuous loop. Although the staircase is conceptually impossible, it does interfere with your perception since it looks like a person could climb forever and never get any higher.

Watching the video is the easiest way to see how it works. I’ve included a drawing which is linked in the video description.

Step 1: Tools/Materials

Tools:

  • Band Saw
  • Tape measure
  • Pencil
  • Clamps
  • Sander (optional)

Materials:

  • Wood 1 x 6 or 1 x 3
  • Wood glue

Would you be wiling to make the 3D model which was shown in the video clip available?

Sure. Note that the drawing is linked in the video description. It's a very simple model so I'm not sure how much time it would save you. I can email you the inventor and/or STEP files. Let me know if you want them.

Check this out for a similar project - with a working waterfall!

I remember hearing about people creating similar things (Escher art) in 3D about 15 years ago, but I never got to see the renders. This is perhaps a little more interesting :) Thank you for sharing.
