A Singaporean scientist captured the imagination of hundreds of technology junkies when he showed off his "invisible cloak" technology earlier this week at a California tech conference.
Dr. Baile Zhang, an assistant professor of physics and applied physics at Nanyang Technological University in Singapore, unveiled his innovation at the 2013 TED conference in Long Beach on Monday.
The device itself frankly does not look like a cloak but its ability to bend light so it cannot be seen left conference attendees spellbound.
Dr. Zhang's contraption can be seen in a demonstration posted on YouTube. The minute-long clip shows a box made of two pieces of a light bending mineral called calcite being placed in front of a rolled up pink Post-it note which disappears behind it.
The 31-year-old professor told Bong Bong that he came up with the concept in 2010 just for fun, adding that Monday's demonstration at the TED conference was the first time he showed it publicly.
