When Buckyballs hit stores two years ago, the tiny magnetic metal globes that you mash and mold together became a hit with office workers, including some of us in the Inc. office. Now, Buckyballs creator Jake Bronstein has unveiled Buckycubes, a square version of the desk toy.

Instead of mashing the squares like Buckyballs, you fold, bend, slide, and snap them together to form different shapes. Maxfield & Oberton, the company that makes Buckycubes, sent a set of them to the office last week, and I’m quickly becoming addicted.

Buckycubes will be available for $24.95 a set at Brookstone stores nationwide and on Buckycubes.com in October.
