If you’ve ever wondered what thinking about nothing looks like, here it is. It’s the result of an experiment by artist Gustav Metzger, who hooked himself up to a robotic carving machine—while thinking long and hard about absolutely nothing.
The machine takes EEG signals—essentially the electrical signals from the brain, measured through the scalp—and then uses them to dictate the patterns it cuts into a piece of Portland Stone. The result’s rather beautiful, and itself looks like some kind of abstract artwork depicting a human brain. The sculpture is on display at the Work Gallery in London until February. [Design Week]
