I don’t know about you, but this is one freakily awesome Halloween costume. If you have a pair of iPad 2s lying around, you could put them to work and create an illusion of a huge hole in your torso. How? Dead simple, says one Mark Rober, a NASA employee. Just strap one iPad to your front and the other to your back and start a FaceTime chat between them.
The front iPad will display live video feed recorded by the back camera of the device strapped to your back and vice versa. The effect is totally believable, as if someone shot a hole through your body. Spray a little red paint around cutouts in your T-shirt and paint some gruesome flesh parts and you could easily become the star of this year’s Halloween amongst your geek friends.
