We have made a spinning spokes optical illusion for you. The illusion asks which way are the brown spokes in the middle moving? If you let your eye follow a green spoke around with a brown spoke underneath they both go the same way. Now if you follow an orange spoke with a brown spoke on top, they both go the opposite way.

Stare intently at the blue spot for at least 20 seconds then look away at a white background and a famous Klingon will appear. yIlop! wa'leS chaq maHegh!

Today we have uploaded a new post in the spy blog detailing the history behind the creation of one of the world's greatest and most famous illusions - Akiyoshi Kitaoka's Rotating Snakes.

Which line is longer the red or the blue? We think you get this one fairly easily.

We are adding four more illusions to our Erik Johansson Gallery today. Be sure to check out the whole gallery.
By the way, the last two pictures will flip if you hover over them (desktop machines only I fear).

There is no blue in this optical illusion. What looks like blue is actually green and strangely enough its exactly the same shade of green as the other green. Wow!
Inspired by  Akiyoshi Kitaoka's Spiral

This illusion has gone viral today. Is this dress Black & Blue or White & Gold? In my house the women say White and the men say Blue. What do you think? Thanks to Masodo over at Blogdogit for the headsup.

What a great piece of 3D illusion art landscaping, check out how it was built from individual tiles here - Deformscape

This great picture just shows how we can all be fooled at first glance. Of course once we really take a good look it is pretty obvious that it is just an excellent mural. Find out how it was done over at Lushome.com

This old picture shows three cherubs, but a closer looks finds seven boys, can you spot them. If not then click on the picture to see them all. Original image source unknown.

A couple of nice space ships for you today. But what's going with the background is it stopping and starting? And when the spaceship flyies away do the stars start moving anticlockwise?

How many arrows in the above optical?

I have got a feeling this optical illusion might just blow your mind. We have put three clusters of circling balls above, but can you tell me how many of the three are going in the same direction? If you stare at the center yellow spot of the top left cluster they all seem to be going the same way, but not if you look at the other yellow spots. Let me know what you think in the comments.

You might have seen a similar illusion with our Optical Spy Owl - both modified from an unknown image.

Hello guys, I've got a great old favorite illusion for you today. Take a look at the Optical Spy Archway. Someone has put a post right in front of it, but look at the top of the arch, will the two sides join at the top or not? You can click on the picture to find out. But before you click let us know what you think is going on here in the comments, we would love to hear from you.
We would also love to see any of your illusions or strange photos, you can upload these to us here. We look forward to hearing from you. - Spyman
