What you see below is a great find by Neatorama blog. It looks as if there are doors in a concrete wall, but actually – there aren’t any. The doors are in fact a flat mirror designed by Sarah Dayo that creates the optical illusion of wall opening. The only problem with today’s post, is that once you spot the illusion there is no going back. Sarah writes:

Sometimes we cannot help but to try and catch a glimpse of the other side. Passing through the everyday spaces we inhibit, the door half opened always stirs up a sense of seduction and curiosity within us. Inspired by these ordinary yet inexplicable moments in our daily lives, I designed a mirror that gives an illusion of a door opening on any given surface.

    that was awsome until i read your discription then i was able to see it from another point of view. first comment Yahoo.

    I looked at it for about ten seconds then seen the answer. btw ii’m not stupid, i looked at it without reading the description.

    Awesome! That is very well done!

    I can see the shadow of the mirror against the wall. It was not readily apparent. At first it does look much like a door opening but where the angle point should be there is no line or any change in brightness where the lighting should be due to the differential in the angle of the surfaces. Nonetheless it is an amazingly realistic illusion.

    Mirror Mirror on the wall,
    Who’s the coolest one of all?

    You, V.

    Nice. The thing that made me suspicious straight away was there is no crack on the right hand side of the door. If that got added, it would be a lot more convincing.
    The othe problem with these sorts of art works is keeping them clean, any dirt spoils the illusion. I’ve seen similar tricks used to make small gardens bigger.

    i can see the answer and i can stillsee the illusion

  9. Phoenix says:

    I agree with Melinda, it be very cool to be able to pop it anywhere and make it seem there is a door there. Mind you one can just cut a mirror oneself. Great illusion!

    Somehow I can always go back to how I saw it the first time I looked.

    “The only problem with today’s post, is that once you spot the illusion there is no going back.” Why tell us it’s a mirror in the description then?

  12. randy says:

    very nice…btw lets give it up for natalie huh…

  13. Jacob says:

    i thought it was a slab of concrete with a door-y shape in it…then i saw the shadow on the edge of the mirror

  14. Jack says:

    I don’t see it.

    Can someone explain?

  15. Awsome!!…..It’s all done with mirrors. Good illusion.

  16. Jessica says:

    I saw the mirror first and actually had trouble seeing the door- not my favorite illusion

  17. t says:

    YAY! Art and illusion together. I love it.

  18. Elevown says:

    Good Illusion :)

    But I disagree about no going back.

    If I focus on seeing the weird shaped mirror, its shadow etc then I see that- but equally if I consentrate on the ‘door’ i can still percieve the illusion just fine.

  19. Norah says:

    I love this illusion, but I was wondering where we would go to send in a good optical illusion. It’s actually a video but it has a lot of illusions I haven’t seen on here before.

  20. Piyush Koshiya says:

    Door is open 50 %

  21. Mona says:

    I absolutely don’t see what the big deal is. and it feels like being left out of a good joke.
    There’s just a kid standing at a concrete wall with a door ajar. What should I be seeing?

  22. That’s beautiful. But it’s sad that you lose that sense of fantasy that Sarah is talking about once you do see the illusion.

  23. Nick says:

    I thought that the concrete actually had a hole in it at a slight slant creating the effect of a door.. but once i read its a mirror.. whoa.blew my mind.

  24. Latisha says:

    Wonderful , WoW , this is definitely one of my favourites

  25. Voigt says:

    Very clever. I agree, I would like to get one for my house!

  33. Vincent says:

    At first, I thought there is a door.
    At second, I thought it was paint. I can still see the door
    But now, I know it is a mirror! I can’t see the door anymore!
