With the Space Shuttle permanently on blocks, NASA mechanical engineer Mark Rober has some time on his hands. So, after killing the Halloween game three years ago with his digital "Hole in the Chest" iPad costume, he's back this year with a whole bunch of new versions that use iPhones for creepily real, bloody effects.
