One way to take advantage of wandering cursors is to turn buttons, images, text, and more into interactive elements that response to the user’s cursor movements. These graphics can move, change colors, reveal hidden illustrations, or cause ripple effects all from moving the cursor around the page.
Many websites don’t give the cursor tracking elements navigational uses, and the animations are added to places like the footer to give a little life to the site. These fun animation bonuses can reinforce the sites branding, while giving users motivation to stay on the page just a few more moments. They’re the kind of Easter eggs you waste an entire lunch break exploring.
