A few weeks back, with collaborators Priscilla Heard and Christopher Tyler, I won second prize with this movie in the annual Best Visual Illusion of the Year Contest.  I think we were lucky!  As ever the competition showcased some fascinating, quite new illusions, and this year’s were a particularly strong bunch.

Extra – July 2019 – Earlier this year we published a paper analysing the illusion  in the online, open access journal i-Perception.

Last year the competition organisers published a beautiful book, showing some of the illusions that won prizes in the years since the competition started in 2005.  You can see details on this site.
