I recently came across an interesting effect on the IconArchive website, but I am unsure how to implement it. If anyone could help me understand the concept with a small example, that would be greatly appreciated. You can see the effect in action by visiting this link: http://www.iconarchive.com/search?q=share&page=3. When you hover over the heart image, a copy of it moves to the bottom and adds the icon you have selected. I suspect that JavaScript, jQuery, and CSS were used to achieve this effect. Unfortunately, I do not have any code to start with.
