I’ve written in my New York Times column about how I use optical illusions with English Language Learners, and I certainly use them when teaching perception in my Theory of Knowledge class. You can many that I’ve previously posted here.

The BBC has now published what is probably the “be all and end all” of resources on optical illusions over the years. It’s titled How your eyes trick your mind and will certainly come in handy.
