Crazy letters


In the picture, letters are embroidered on check material with yam which is twisted from a black and white thread. Do you have any doubt that the letters are sloping!

A ruler will show that the letters are straight. Because of the sloping bars in the back- ground and the twisted threads, our eyes experience a confusing shift in the outlines of the letters.
