Here's another one - shows it works in colour too! The 'yellow' square in the middle of the front face and the 'brown' one in the middle of the top face are the same colour. They are. They really are.
In some ways, examples of how our visual perception can be mislead are simple enough to get your head around. Perhaps it makes you wonder, though, how much of your other perceptions are distorted. Can you think of an argument, for example, when you and another were both convinced that you were right about something, even though you disagreed?

Hi, I didn't know you had a blog, too! This looks very interesting!
Don't get this; they look totally different!
Yes, they do look completely different, don't they! The reason is that our brains automatically compensate for lighting conditions. For example, when we see things under artificial light, they don't change colour and look more orange. And when a white surface is in shadow, it still looks white to us.
In the cube illusion, it appears that the nearest face is in shadow, so our brains automatically lighten and adjust the colour we see. What is hitting the retina as brown gets converted into yellow.
Someone on a website I came across suggested using art or photo software to cut out the two squares and put them next to each other...
