Pulsating Nightmare Optical Illusion

Originally titled “Here comes another seizure“, the disturbing background pattern used in this tremendous optical illusions comes from David Ponce’s evil laboratory. I don’t know about you, but there’s something quite disturbing about it – it is as if I’m becoming more and more nervous while looking at it. Pink Floyd’s “Dark Side of The Moon” cover was just plastered on top to make the illusion more interesting and spooky. It helps with focus and strengthens “pulsation” as well! Not sure what’s causing the illusion to be frank, but I suspect it has something to do with our eyes’ microsaccades (small involuntary eye movements we all experience, but usually don’t notice). When you’re finished with this one, check out the following gag!
