Here are some cool Optical Illusions. Some images looks real trippy, some images does not appear as you think they are. Very nice illusions, enjoy!
Stare at the middle of this image for 30 seconds and then look somewhere else, blink your eyes for a cool effect!
This image seems to be moving when you look at it, move really close to your screen and you'll notice that it's actually not!
How many shelves do you see here, three or four? :)
Stare at the dot in the center and move your head in and out.
This is really a cool illusion, how is this possible? :)
