Pyramid Pillar Illusion
Category: Double Meanings | Added: September 26, 2009

This photograph taken in Bad Langensalza, Germany shows one of many pillars placed around a fountain. The illusion here is that the pillar can either appear to be hollow or to have a pyramid on the top depending on which way you look at it. The shadow on the right gives it away slightly but its still quite convincing.

Cool I see both !!!! But is hollow, the shade gives the impression to have a pyramid on the top.a

at first it really looks like a hallow but when i saw the shadow on the side that overlaps, then, i knew it has a pyramid on top...

As the thing said, the small shadow on the bottom gives away the fact that It's a pyramid, but when you look at the top, it appears to be hollow. Very neat!

Haha are you kidding people it is a pyramid on top if you knew anything about light source you would take notice of the placement of the shadow. if it were hollow how would the be a shadow on the outside right but not on the inside left side.Plus you can see the shadows from the point on the outer lip. Not Hollow.

I think it\'s sticking out because in the top left corner toward the middle there is an extra line plus the shadow on the bottom left is sticking out farther than the square lines

Its sticking out! The shadow would make it stick out. You can also see part of it on top of the pillar
