James Thomas Fields has created a very strong optical illusion effect, which gives the illusion of appearing and disappearing spiral lines. Just look at the pattern James originally shared via our FB channel. First time you look at it, there is a big chance you won’t go into details. Now if someone hid the picture from you after a moment and asked from you to describe what you have just seen moments ago, your answer would probably end up something like this – “I think it showed a spiral that narrowed down to a central white spot. At the same time the spiral was covered with some kind of ying-and-yang overlaying pattern.” Even though not far from truth, the real deal is that there were no actual spirals present at all! Now if you look at the picture once again, and try and focus on the seemingly present spiral lines, you’ll soon discover there really aren’t any… Good job James!
