The two images of the Leaning Tower of Pisa are identical but it gave an impression that the right tower leans more than the left… simple yet amazing. [Why?]

An interesting 3D drawing by street artist Kurt Wenner, at the Waterloo Station in London. The artwork uses perspective tricks to make it “pop up” in 3D when viewed from a certain angle…

Optical illusion… read the words between the blocks. If you can’t read it, just get off your chair and try reading it a metre (or two) away from the screen.

Spinning Silhouette Optical Illusion

Yein Jee — Mon, 30 Jul 2007 06:36:56 +0000

This is one of the coolest optical illusions I’ve seen (a bit tough as well).

Most people will see the girl spinning clockwise initially… but the girl can be seen as rotating anti-clockwise as well, depending on how you see it.

Tips – focus below the hip to ‘change’ the direction; if you still couldn’t see it after some time, cover the upper body part and just focus on the legs.
