Presentation Transcript
spot the giraffe
• If you stare at the following picture long enough, you should see a giraffe…
PINK dots
• This one has a couple different cool things. First, if you follow the pink dot moving, the dots will remain pink, but if you stare at the plus sign in the center, the rotating dot will turn green.
• That’s cool, but now try this... focus on the plus sign in the centre for a short period and all the pink dots will disappear and all you will see is the green dot going around! cool huh?
black dot
• Stare at the black dot...
• after awhile, the gray haze around it will appear to shrink.
DOTS
• There aren’t any black dots in this image.
Checker board
• Which box is darker - A or B? Seems obvious doesn't it?
• They are both the exact same colour!
Parallel lines
• The lines below are slanted right? Actually, they are perfectly parallel! Now that is hard to believe.
How many legs?
• Can you tell how many legs this elephant has?
How many?
• And here is another type of illusion.
• Count the people in the picture below.
• After they shift, count them again!
Moving?
• A static picture – not animated!
Native American profile
• A Native American profile?
• Or an Eskimo entering a cave?
the reversing staircase
• Stare at the Reversing Staircase Illusion until
• it changes to a different staircase.
Which looks bigger?
• Which of the MIDDLE circles looks bigger, the one on the left, or the one on the right?
Good or … ?
• Let’s play with some words – what do you see?
