Photo Illusions are creative ways to confuse your mind and create false perception of things that don't exist. There are tons of funny photo illusions out there ranging from exploiting false perspective (eg. catching sun in hands during sunset, holding the tower of Pisa etc.) to paintings on walls making the impression that there is no wall but rather we see what is inside the building.
The mentioned paintings are actually called "trompe l'oeil", which comes from French and means "deceive the eye". You might have seen such murals fooling us into seeing 3D scenes which are painted on a regular flat wall. It's funny how we like to be tricked.

Let's have a break - turn your head to the right to see what really happens.
Will you merry me?
You may choose the woman's look that you like the most. Funny illusion, isn't it :-)
I highly recommend checking out also other 3D murals painted by John Pugh. He can create great 3D illusions on a simple wall. Another great artist, Julian Beever, prefers sidewalk for his 3D art.
Any other funny ideas for balloons?
