Today's technology is downright frightening

Combine a new technology with the creative mind of a rocket scientist, throw in Halloween and the results are pretty amazing.

When Apple introduced the iPad in 2010, it didn't take long for Mark Rober, a one-time NASA engineer who helped put the Curiosity rover on Mars, to come up with a Halloween costume idea that incorporated it.

For Halloween 2011, Rober showed up to a party wearing a shirt with gaping "bloody" holes ripped into the front and back, and iPads attached to the inside, visible through the holes. By setting up a Facetime video link between the two, he created the illusion of being able to see through his body.
