The Puzzling Place World of Illusion has many fun, if tired-looking, optical illusions to explore and interact with, including an "Anti-gravity Room", an Ames Room, a Hologram Gallery and and an "Eyelusions Exhibition".

 

This simple yet intriguing exhibit caught my attention as the largest object seems to float in space due to balance of forces acting upon it.
