Be sure to notice how part of the painting is a pinned down painting itself, motive Sandro heavily uses in his works. How many optical illusions can you spot in today’s post?

Btw, those of you still reading, I would appreciate if you had a second to spare… My mum has tailored a coat which she feels very proud of, and had submitted it for a competition of some kind. She isn’t aware I’m writing this, but I would appreciate highly if you could rate her design positively here (click “J’aime” if you like it).

Never the less, I think the illusion in its essence is perfect. Moreover, it became even more interesting when I noticed the second illusion it hides. It took me few moments before I realized that the central column isn’t the only Escheresque object present. Perhaps it’s central placement and focus distracts people’s attention from noticing the second illusion, which isn’t much different itself.

How long did it take you to realize them both? There were some other posts on this site, that showcased real-life Escher Columns in action as well. Unfortunately, I can’t decide which were the best cases. Help me, and post a link (or attach image to your comment, if you wish) to your favorite ones!

Oh, I forgot to tell you I booked a hotel in NY, Manhattan and will be there in October with my girlfriend. Are there any New Yorkers here that can advise me what to see, where to go out, and how to get those hard to get tickets for NBA/MLB etc? Anyone wants to be our guide when we arrive?

Can you spot where the ships become arches, and vice-versa?

Impossible Arch Puzzle

I found this image in my optical illusions folder today, and wondered why I never got the time to publish it. Look at the picture on your left. What do you see? There must be something strange going on here. No way that the arch shown here has the proper top. Or can it? I’ve also included a solution inside this post. You’ll have to click the expandable box to see it. I wouldn’t want to ruin your solving experience before you’re ready to see the answer. Anyway, by looking at the solution everything becomes clear. Why has our brain presumed the column is aligned differently than it actually is? I really can’t tell, but hope some of you will try and explain this through comments.

Yesterday I tipped you about new Facebook vanity URLs. Have you had the time to check them? Hope you managed to grab something short and unique to represent you, like I did. But it seems not many of you actually read what I post. Probably you check only the illusions, which is also fine. But I’m REALLY curious what names were taken by our audience. Would be very nice to see more and more of you using your facebook logins to post comments. Not only does this automatically shows your image next to your comment, but additionally you have an option to share your comment so it appears in your Facebook feed. This way you can help us reach more people (your friends will see that you left a comment on our site, if you approve it). What is your opinion on this?
