Optical Illusions Blog
A blog about Optical Illusions, etc..
Some of the optical illusions on this website can cause dizziness or possibly epileptic seizures. The latter happens when the brain can't handle the conflicting information from your two eyes. If you start feeling unwell when using this website, immediately cover one eye with your hand and then leave the page. Do not close your eyes because that can make the attack worse.
Signing Off. Until next time, I'll see ya on the Blog! drh.
