Hover Web Page Preview
Denver IT. Ghost-O-Matic. This demo shows how to add live mini-previews to links on hover. Check out this link to Codegena. Hover over it to see a small preview of what it points to.
Those previews were fetched as soon as this page loaded. This is great for having the previews ready ahead of time, but can eat up extra bandwidth. As an alternative, check out these links to Youtube Embed Code Generator and iFrame Generator. These previews aren't fetched until you hover over this paragraph.
