   Cool illusion. All 8 horizontal lines are straight, although they seem to taper at each end.

   The horizontal one's are all straigt. They just seem to be tilted due to the distortion of the black squares.

   8 lines. It's an optical illusion that is pretty well known nowadays. It's pretty funny how the human brain cant handle the information.

   9 if you count the line that isn't drawn across the top!
   
   I always thought the flag illusion was crazy, all those rods and cones getting wild on color recognition.

   I just see 8 straight lines the others are not straight because it is slant. So probably it's 8 straight lines.

    There are no straight lines, most of the lines are curved or bent.
    
    Ok.
    
    How will you answer or tell how many lines are there?
    
    You want to know from other hubbers or you are asking puzzle?

    i didnt bother counting, but maybe you can make a short equation - there's a lot more than just 8 straight lines here
