Art Lebedev gave the world the first keyboard full of customizable displays, as well as a multitude of shipping-delay headaches. After the Optimus Maximus was released to mostly favorable reviews, we all wondered what came next.

Would it be a mouse with display screens or a touch monitor for Photoshop enthusiasts? Alas, no. A door chain lock was the next step. Really, we all should have seen this coming.

Design firms like Lebedev are playful, contrarian, and terrible teases. They come up with a beautifully designed piece of hardware and the next time, they’ll make you play in an abusive labyrinth of time mismanagement. But despite our disappointment with the lack of a Photoshop screen, we can appreciate the simple madness to come up with this thing.

After all, when dealing with potential burglars, it’s just as important to not be able to open the door from the inside of the house as it is from the outside.

The Lebedev Defendius Door Chain is made from 100% Titanium Alloy Construction, and has been tested to handle 700 lbs. of force. Grandma will love it.
