Have you seen these  hypnotic, strangely beautiful GIF images yet? At a rate of roughly two a week, they've been appearing on a Tumblr blog called rrrrrrrroll that is dedicated to the project and run by a group of friends.

Sometimes it's a young woman spinning on an axis, at the unhurried pace of a ceiling fan set on low.  Other times it's an object — an umbrella, or an electric rice cooker, for example — set in motion. A simple concept, yet undeniably captivating.

According to the group's Facebook page, the blog has attracted more than 10,000 followers. Not too shabby for a group that only started uploading photos in April.

And a hat-tip to Tofugu for the find . . . though it was Huffington Post  that first shined the big light on the rrrrrrrrollers.
