As a kid, among my favorite books on my parents’ bookshelf was Light and Vision, from the Time-Life Science Library. 
. And my favorite part of the book were the optical illusions, such as the two-pronged object that somehow morphs into 3 cylinders, or the square of stairs that go up forever. (And, yes, I had MC Escher posters in my dorm room.)
As such, this blog dedicated to “Optillusions” is my new favorite thing.
Hi Peter,
