What colour is the dress?(1) blue and black(2) white and gold(3) other
The dress is a photograph that became a viral internet sensation on 26 February 2015, when viewers disagreed over whether the dress pictured was colored blue and black, or white and gold. The phenomenon revealed differences in human colour perception. https://en.wikipedia.org/wiki/The_dress
How many black dots do you see?
I couldn't look at this the dots keep flashing!
That's the illusion, because of the way that the squares and the gaps in between them are positioned, it makes the dots appear to flash or jump so that you can't actually count them.
These websites explain about the psychology of optical illusions a bit:

Leave it up, it is a great illusion
I'm glad that it's going. I wonder if I should take the picture down as I don't want to give lots of people a headache? Mind you, I don't think that I will be able to delete it now that people have responded to it :-(
It's going, it's my own fault I know looking at things like that trigger it, but I still do it!
