Description Presented here is a vast gallery of many different forms of Optical Illusions. Whether these optical illusions are conveyed through fractals, photographs, architecture, art, or old fashioned pen and ink, they are bound to remind you that "seeing is not believing."

Caution!!!! Some of the optical illusions on this blog may cause dizziness or possibly epileptic seizures. The latter happens when the brain can't handle the conflicting information from your two eyes. If you start feeling unwell when using this website, immediately cover one eye with your hand and then leave the page. Do not close your eyes because that can make the attack worse.

Fountains Abbey Obelisk Illusion

This is the third item that Dave Barlow sent me. He took this photo while on holiday at Fountains Abbey, UK, last year. When he got home he realized there was an illusion that the obelisk seemed as tall or taller than the church.

My question is, how tall is the obelisk seen here?

Taller than the church?
As tall as the church?
3/4 as tall as the church?
1/2 as tall as the church?
1/4 as tall as the church?
