Spine Drift Illusion

Was just wondering what’s been going on with our Japanese professor #Akiyoshi Kitaoka lately, when I received this amazing submission from one of our fans – featuring recent work done by our favourite professor. Yes, similar illusions were featured in the past, yet the inset in this one just won’t stop moving! I’m not sure you’ll be getting the same results I did, specially since your “tiredness” factor heavily influences the motion… BTW, you might want to slightly scroll the picture up and down, or tilt your head around to experience even stronger effect!
