These images have been circulating on the net for some time, I and several of my coleagues got them through e-mail. So I hope it is safe to assume they are in the public domain and no-one will be or feel hurt by my compilation here.
This one for some reason almost hurts to look at.

Do you start to get dizzy yet? Is it an animated image, or not?
If your eyes follow the movement of the rotating pink dot, you will only see one color, pink. If you stare at the black + in the center, the moving dot turns to green. Now, concentrate on the black + in the center of the picture. After a short period of time, all the pink dots will slowly disappear, and you will only see a green dot rotating if you're lucky! It's amazing how our brain works. There really is no green dot, and the pink ones really don't disappear. This should be proof enough, we don't always see what we think we see.

Look at the chart and say the COLOUR, not the word!
Your right brain tries to say the colour but
your left brain insists on saying the word
Count the black dots! :o)
Is the left center circle bigger?
How many legs does the elephant have? And how many feet?
Keep staring at the black dot.
After a while the gray haze around it will shrink.
Are the horizontal lines parallel?
Focus on the dot and move your head forwards and backwards (closer and further from the screen). Weird... %-/
