The Elder Wand and Resurrection Stone may still be locked away in J. K. Rowling's imagination, but the third Deathly Hallow made a rare appearance on stage in Long Beach this week.

Baile Zhang, an assistant professor of physics at Nanyang Technological University in Singapore, showed off his "invisibility cloak" on Monday at the TED2013 talks in Long Beach.

Speaking as part of TED Fellows Day, when young researchers, artists, and techno-geniuses seen as being worthy of mentoring give short four-minute presentations, Zhang wowed the crowd with his amazing cloak.

As you might guess, Zhang's cloak is a bit different than the one Harry Potter wore. It's tiny right now, very much in the prototype phase. And while you might expect it to have some grand purpose, it doesn't. Zhang created it solely for fun.

Speaking with editors at Boing Boing, Zhang explained that the cloak is made of two optical crystals that are found in nature. When cemented together, they bend light and suppress shadows to the point that they can hide objects. The demo at the show saw the cloak (which is kept in a tiny clear box) make a Post-It note vanish.

The TED talk was the first time Zhang

Was this invisibility cloak sitting on a glass invisibility plate? so... refraction? is this why the [s]orange rod[/s] pencil is never raised?

edit - yea around 12-13 sec you can see its a glass cube with a half hole the orange rod threads through.. debunked merely as an optical illusion. Maybe theres some tech to it as there should be an orange tinge, but I'm not ruling out lights camera angles and glass plates. Its 2D cloaking at best :)
