Sight and Sensibility - Just Clowning Around
This is a "moo-valous" picture.
Can you see the cow?
Are the black sides inside or outside?
Which arc comes form the largest circle?
They are small segments of the same circle.
Which man is the tallest? They are all the same!
A duck or a rabbit?
A young woman or an old woman?
An awning or a circus tent?
Print this picture, cut out, and spin. The design will pulsate.
A young woman or a grouchy clown?
Are the holes on the top or inside?
