Fun stuff to do
Optical Illusions
Your eyes can play tricks on you. Pictures that confuse your eyes and brain, tricking them into seeing something differently, are called optical illusions. See if you can figure out these optical illusions.
WHICH OBJECT IS TALLER? (None: They’re all the same size.)
WHICH LINE IS LONGER? (Neither: They’re both the same.)
IS THIS GRAY HAZE SHRINKING?
(Stare at the black dot. After a while the gray haze will appear to shrink.)
DO THESE COLORED LINES BEND?
(No, they’re perfectly straight—but try telling your eyes that!)
ARE THESE WHEELS SPINNING?
(Stare at the center. Now move your head back and forth toward and away from the page. The circles will appear to spin.)
HOW MANY BLACK DOTS CAN YOU COUNT? (Look closely and you will see them.)
DO YOU SEE TWO FACES OR A VASE?
(If you see one, close your eyes for a moment, then look for the other.)
ARE THESE LINES STRAIGHT OR CROOKED?
(Yep, you guessed it. The horizontal lines look crooked, but they are perfectly straight.)
ARE YOU SEEING RED, WHITE & BLUE? (Stare at the center of this flag for one minute. Then look at an empty white sheet and you’ll see a red, white and blue flag.)
HOW THIS FLAG WORKS
Your eyes see color as measures of red or green, blue or yellow and bright or dark. When you look at a green object for a long time, your eyes get tired and start seeing red. When you look at yellow, after a while you’ll start to see blue. And darkness turns into brightness. The result: Even this wacky flag can be good, old red, white and blue—after a while!

Has anyone seen the one kinda like the flag, only you see Jesus?
They probably used the flag because the world expects us to be secular.
Sigh.
