Che Guevara Afterimage Illusion
Stare at the image of Che Guevara below for at least 30 seconds and then look at a blank surface or close your eyes. If you close your eyes, it can help if you look toward a light source such as a window or a lamp. What do you see?
If you enjoyed this illusion, you may also want to revisit the Jesus illusion, which produces a similar effect.
