Virtual Caveman Becomes Humankind&#39;s Newest SlaveS  Cavemen
aren't just useful for stupid Brendan Frasier movies and Geico
commercials. Scientists at the University of Calgary created a
giant virtual hospital patient called CAVEman—CAVE is an acronym
for cave automated virtual environment—and made him a guinea pig
for all things anatomical.  Virtual Caveman Becomes
Humankind&#39;s Newest SlaveS  By collaborating with graphic
artists, the scientists made 3-D images of everything from the
funny bone to the kidney to each nerve in your brain. Then, they
recreated these body parts using a projector. CAVEman started
off as someone who got free massages all the time—he was
originally created for massage therapists in training—but now
he's become the virtual environment for MRIs and biopsies. The
future doesn't look so hot for him, either: in the next phase,
they're going to put tactile feedback sensors on him and make
him simulate respiration and blood flow so they can test cutting
edge treatments on him before
