O.D. (Optical Delusion) by Aaron Paterson

Basic effect description:
Let the audience think of a card in 52 cards. The magician took out the mobile phone with the camera and took a picture of his own eyes. Then let the audience stare at the eyes in the photo, and the incredible thing happened.
When the audience stared at the pupil of the eye in the photo, a card gradually formed and disappeared, and formed again. Finally, the audience was surprised to find that the card in the photo was the card that I just thought, and it looks like the magician put the audience. The idea was extracted from his brain.

Any mobile phone, as long as there is a camera suitable for performance
I can repeat the performance right away, and it’s not the same result.
Once ready, it’s very easy to perform
