Masks are required for all visitors 2+. Vaccines recommended. Plan your visit
Turn a flickering light into a complete image in your eye.
Can you see pictures in the air?
Which is in control, your eyes or your brain?
Make a bright spot brighter.
What happened to your whole hand?
Eye'll be seeing you.
A colored object may look different against different-colored backgrounds.
A face seen upside down may hold some surprises.
Make the palm of your hand appear to squirm and twist.
