I love the street paintings. Have seen them before and always think they look amazing. Once saw a few on holiday, and even up close they looked really realistic, takes some talent to do them.
For this optical illusion to work, stare at the center crosshairs and move your head in and out from the screen. Sometimes when you just look to the side or relax your eyes a bit, you'll notice the spiral moving.
Can you remember back in the early '90s, they use to be a craze of these pictures called 3-d images. I use to like doing these,as well has the optical illusions.
I used to like the 3-D images.......I'm sure that's why my eyes are 'cream crackered'........hubby used to tell me it wouldn't do my eyes any good at all.
i have a book on the pictures called magic eyes, you have to stare at the picture and after quite a while an image appears on the page and when your transfixed on th picture you can actually move your eyes and take the whole picture in, there so clever! next meeting we have and any of you turn up let me know and i will let you all have a look.
This has been on before but I can't find it, so...
This is an illusion that has been around for a while, but never ceases to fascinate. Relax and concentrate on the four small dots in the middle of the picture for about 30 to 40 seconds. Then take a look at a wall near you, or any smooth, single colored surface. You will see a circle of light form. Blink your eyes a couple of times and a figure will begin to emerge.
