Optical Illusion's Picture

Continuing from previous entry here, Optical Illusion Hidden Pictures, pictures below are just illogical, right?

These pictures trick our mind into some optical illusion, especially the last 2 pictures.

Up and down, which way to go?

How about this one?

Here's another one

Is it a square or a circle? Try focus at the X in the middle

Yes, there are lots of other pictures similar to these ones here, out there (I mean on the internet), just google image them, you'll be amused by all sorts of optical illusion and mind playing pictures.

As if its not enough, try search for video on youtube for these sort of theme.

Click here for the google images, here for the youtube.

Have a nice day (",)
