Still, the cloaked area was only 30 microns wide, or about one-third the width of a human hair.

Now researchers have developed a cloak that can hide three-dimensional objects against red and green lasers and ordinary white light. Although the cloaked region they demonstrated is only three-quarters of an inch (2 centimeters) wide, 'there is actually no limit on the size of the cloak,' researcher Shuang Zhang, a physicist at the University of Birmingham in England, told LiveScience."
