We came across the best, geekiest Halloween costume, ever.
An engineer at NASA named Mark Rober used two iPads FaceTiming each other to make it appear he had a hole in his stomach.
The only problem is that you need to be somewhere with Wi-Fi for the system to work. (Or you can do what Rober did and bring along a MiFi personal hotspot.)
