Google appears to be testing a new YouTube feature that triggers the company’s now rather familiar card design when rolling over a channel link.

Spotted by Google Plus Daily (via Google Operating System), it’s possible for anyone to take a sneaky peek simply by typing this little piece of code into the browser’s developer console:

document.cookie=”VISITOR_INFO1_LIVE=0xJL6SMMUyE; path=/;”;window.location.reload()

Rolling over a channel link then reveals a small card which shows the YouTube channel’s cover art, name and a subscribe button, alongside a link to the creator’s Google+ profile.

This is what it looks like in action:
