The Shepard Tabletop Illusion
What to see and do: It appears that the tabletops are different shapes and sizes but they are the exact same size. Click the SHOW ME button to see. Click the RESET button to change it back.
What's happening: The table tops look like they are different sizes because one view looks like you're looking at the end of the table and the other looks like a side view.
