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 is 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]
