CSS Pranks
summary
A small browser extension injects site CSS systemwide after Chrome deprecates its custom CSS file so a prank can apply to any visited page. Demonstrated effects include grayscale 100%, a tiny persistent page rotation, and keyframe animations that spin elements by targeting .logo and #logo selectors. A slow 1-minute hue-rotate animation and forced slow transitions make changes subtle but disorienting. Examples work live on Google and other sites and reliably annoy users when installed on an unattended computer.
