Staggeringbeauty.com

Staggeringbeauty.com is a website that was created in 2012 by George Michael Brower. It features a small black "worm" that follows your cursors movements, and when they become erratic, it causes bright lights to flash and loud noises to play.

Overview
When you go to the website, you will be greeted with a black, minimalist design of a worm with white beady eyes. Upon moving your cursor, it will move with it, and if your movements become quick, it will frantically jerk around as flashing lights and colors are displayed, along with loud music. The website became notorious after many youtubers covered it in their videos.
