Tumblr Labs Allows Users to Test Experimental Features

The Yahoo-owned blogging platform introduced Tumblr Labs in a blog post, saying that users can visit their Labs settings to opt in, and describing the four initial features:

• Themed Posts by @cyle: Changes the color of a post to the color of its Tumblr, turning your dashboard into a beautiful illegible rainbow.
• Reblog Graphs by @idiot: Adds a button on posts that shows you where they’ve been and where they got all those crazy ideas.
