My collection  #opticalillusion received a new addition, namely “Tusi Motion” by Arthur Shapiro and Axel Rose-Henig. Read more here: http://michaelbach.de/ot/mot-Tusi/
        A nice & strong effect, which falls under the general heading of motion binding. I had programmed that already for my talk in Nuremberg in May, but was asked to delay publication a little, now it's here.
