What is your first impression?
A rabbit or a duck?

 

These two striped bars seem to be closer together at the bottom.
Are they?

This " Op Art' cube is strange. Can you see other cube shapes
in the centre of the design?

 

Do you see this as four white arrows - or as a black letter 'H' on a white diamond?

 

Which skeleton looks the biggest?

 

Do you see this as a vase or as two faces looking at each other?

 

Try these two for yourself.

Cross your first and second fingers, now place a marble between them - you should
now feel two marbles - it works better if you close your eyes.

 

 

Fold a small piece of card on a table. When viewed from above and the front with
one eye, at first it appears normal - stare at it for a while and it will appear to reverse, and stand on end like an open book
