Ascending Staircase AnimationThere’s a great chance you’ve already seen something similar, or at least have a vague idea who Maurits Cornelis Escher was. In case you you haven’t, he was the famous Dutch graphic artist, most known for his impossible structures (Ascending and Descending, Relativity…) and various tessellations.

Today’s article features one of the animated variations of Escher’s Ascending and Descending. In reality it would be impossible to construct staircase similar to this one, however there have been some semi-successful examples in the past.

Let’s conduct a simple thought experiment: could you isolate the separation point, supposedly this object was actually a real-life construction instead, viewed from carefully selected angle?

    I think the separation point would have to be at the junction at the back.

    this is a very interesting website. could I ask you something?
    I’d like to know if there’s name for the optical effect you described at the page:

    also, do you know if there’s a software available in order to reproduce this effect?
    thanks.

    i don’t get it!

    If you look closely, he is walking backward along the near wall. This makes him descend to the start again :p

    This is a really clever illusion, but this poor little man has been running around on my screen all day!

    This illusion again! Love it (Kinda)!

  9. I remember this optical illusion from college. It’s one of the better illusion created. I agree with Kelsey, the separation point is at the back.

    Easy if not have same number.

    I believe it’s in the construction of the closest set of stairs. since it’s close it appears to be ascending when it’s actually descending… possibly both long walls are descending. Just was more obvious to me being the front wall. It’s clever use of perspectives.

    The trick is incline steps at a decline.
    two steps up 3 steps down
