I'm always amazed by optical illusions.. here are some stare at one circle and the others start to move.. stare at the moving one and it stops.. and others move both red lines same length? count the black dots!
Some crazy shit... But I never understood abt the "Triangle with hole"... someone explain... unless it's just something different in the drawing
nope.. should i spoil the fun? maybe if someone teach me how to hide my answers.. i can include them in the post
i think i looked at a book with a whole bunch of optical illusions in it and i think i saw the first one somewhere too optical illusions are pretty fascinating o.o
