Screamer Forums and Screamer gallery have returned.
The Screamer Forums will likely remain read only unless it's known that it will be active, since forums in general are kind of dead because of Discord.
Optical Illusion (Jon Shelton)
Optical Illusion is a screamer video posted to YouTube in February 2007. It was made by Jon Shelton (also known as Mad Dad).
Content
The video begins with on screen text reading that you'll be focusing on the screen to witness a dot blurring in and out of focus. The actual test only has a sloppy black dot on a white background that never changes position.
At 0:43, Jon himself zooms into the screen in a dark room as thunder loudly blares. The video ends with the logo for Mad Dad Productions.
