Each Friday morning I post a riddle to get you to think outside the box and exercise your brain.  If you are stumped, share it with a friend or colleague and see if you can figure out the answer together.

This week I’ve put a twist on the weekly post by sharing three images courtesy of LEGO.  To celebrate their 55th anniversary, LEGO has created images intended to serve as riddles. I’ve selected a few below for you to decipher.

I’ll confirm answers in the afternoon so don’t worry if you don’t see your comment posted right away. I want to give everyone a chance to guess.

You can click on any of the images below to enlarge if that helps.

And finally, think of a song…

Each Friday morning I post a riddle or brain teaser.  The idea is to get you to think outside the box and exercise your brain. However, since I am still abroad in Brazil with limited access to my blog, I thought I’d share an optical illusion, which I hope you enjoy.

Amazingly, the horizontal lines are parallel, even if they seem otherwise when you view the image.

So why do the lines appear slanted? This optical illusion is formed by alternating light and dark tiles in staggered rows. In order for the illusion to work each tile must be surrounded by a layer of color that falls between the white and black colors.  This makes most see a somewhat skewed pattern in which the lines are alternately tilted slightly in one direction then the other with respect to the horizontal and in which the tiles appear to be taller on one side than the other.

The grid illusion below involve shape, position and color.  The contrasts converge to produce the illusion of black dots at the intersections.

So why do we see the black dots? The receptive field of the retina light and dark receptors compete with one another to become active.  Once a receptor is active it inhibits adjacent receptors and it is this inhibition that creates the contrast.

This week’s brain teaser:  

This a most unusual paragraph. How quickly can you find out what is so unusual about it? It looks so ordinary, you’d think nothing was wrong with it. Actually, nothing IS wrong with it. But it is not as ordinary as you might think. If you think about it for a bit, you will find out why it is truly so unusual. So what is it? What is so unordinary about this paragraph?
